You mean, in a bag?
I’d do it, but only if getting my hair back was part of the deal. Because I’d look pretty darn odd as a bald headed woman. (And now… great… I’ve that Bee Gees song stuck in my head. “Bald headed woman… bald headed woman to me…”)
“In the butt, Bob.”
The only thing that would stop me is that I’m happily married and I wouldn’t want to mess that up. Other than that, I always thought I’d be much happier as a man. (Maybe I could get the spouse to discover his latent gay tendencies for a cool $125 mil…unfortunately, I’m pretty sure he doesn’t have any latent gay tendencies…)
Does this magic transformation include a working penis?
Same as Infovore, I’m with partners who would not be thrilled for me to show up in a newly female body.
Pretending for the moment that that somehow magically didn’t matter, my answer would depend on the specifics:
• I get converted to the body I would have had if I had had XX chromosomes. And it isn’t permanent, I just have to agree to it for a specified amount of time. I’d be very tempted. Heck, if it was only for a few years you could keep the $250 million if you guarantee me a continuation of my current income. I’m curious, I’ll admit it. I’m genderqueer and I approach being trans in some ways. I don’t have physical dysphoria but it would be nice to see how my life changed via presenting as female.
• Same as above but it’s permanent. Hmmph. What if I don’t like it? Permanent is a long long time. Occasionally I feel like that’s exactly the situation I’m already in, oddly enough: like someone conned me into saying yes to this deal and that’s why I’m male. Anyway, I really don’t know. Consider me highly reluctant at best.
• No magic-wand. Early 21st Century sexual reassignment surgery. I’ll be on hormones the rest of my life. Electrolysis for the hairs, some surgery on the old adam’s apple, still be 6 feet tall and with a male-shaped skeleton. My face would do OK, chin isn’t too prominent, etc, and it would plump out a bit from the hormones. How sensitive and orgasmic is my surgically constructed clitoris? You know something? I am SO SO SO SO glad I don’t have physiological dysphoria. I’m OK with my male body and so fortunate, I think, that this is so. Anyway, this sounds permanent too. No way I’d be wanting to turn the surgeons loose on my bodily tissues to try to go back the other direction a few years later even if the deal didn’t prohibit it. And so it would be even less appealing than the magic-wand version, because I’d be terrified that they wouldn’t do it right and that I would not be happy with the results, you know?
If I could be a smoking hot woman I might do it even cheaper. If I look like me now, except in drag, I’d need 250M minimum. 
That’s what’s stopping me as well.
OK – not really. I’m not great looker as a man. The thought of me on the female scale of looks would be like a minus 12. 
Me too. But I’m already 71 and secure in my marriage. And lots of other 71-year-olds of both sexes are minus 12, or worse. Plus: I already have ED, though it doesn’t prevent us from having a fulfilling sex life. But think of how much more fulfilling it would be if I had a functioning vagina.
Hmmm… Do I have to take testosterone as part of the deal? For $250M I think I could live with the “no boobs and dudeparts” aspect, but if I have to have ghastly facial / body hair, then no dice, unless I can get magical 100% effective full-body electrolysis the day after the plumbing switch…
actually I had a couple of girls who preferred other females over the years say I should of switched then id be perfect for them …
I never was a girly-girl anyway. When I was a kid people would always be telling me girls couldn’t do whatever I wanted to do. Too bad I couldn’t get to be taller while we’re at it, though.
Am I the only one surprised that “No” is beating out “Yes” by a fairly substantial margin?
With my luck, there’d be an apocalyptic economic event which would leave me with a pile of worthless money and a fake vagina.
why would that surprise you?
No, I want it back on and functional. 
I think that means you’re saying no to the offer.
If I’m following the terms and conditions correctly, the first transition is magical, but if you are transitioning back (after at least a year), it is along the lines of what current medical technology can provide.
i’m counting on both the money and the vagina to be very real and substantial. I plan to use the hell out of both.
On further thought, I’d take the 250mil provided that sexual responsiveness was guaranteed. I’m 60, haven’t had a partner in quite a long time. All my sex is solo. If I could still achieve that, while still presenting as my current self…WTH. 250 M would definitely take me through the rest of my life in style. I’d miss being able to whip it out and piss with abandon out in the woods but with all that money I could afford one of those funnel things! 
I think I’d be much more okay with this if it was a magical and complete gender swap, rather than a complicated and harrowing series of surgeries.
