Alton Brown, in his Gear book, tells of his high-speed pepper gun. When he has to grind a whole lot of pepper, he takes the top off a cheapo mill, and he chucks the shaft into an electric drill. Pull the trigger, and you can pepper several huge pots of stew in seconds. 
Another fan of the MagnumPlus. One quibble is with the rotating sleeve that covers the fill hole - it’s not hard to spin it open while grinding, and if the grinder’s chock-full of peppercorns, some might fall out. Beyond that, it delivers a nice grind and a sizeable amount of pepper with each twist.
And chucking a cheap mill on an electric drill? That’s *so * Alton.
I’ve been browsing around for a grinder myself. I caught an episode of “America’s Test Kitchen” a little bit ago, and they also gave a big thumbs up to the Magnum plus. High peppercorn capacity, a good grind, and faster output production than every other one tested (including the electric grinders). They’re only complaint was that it was ugly, but I kind of like the “2001 Monolith” look of it.

We have a Chef’n pepper mill. It’s a one-handed mill, which can be very useful when one hand is gooey or holding something. It adjusts from coarse to fine. It looks like a clear plastic sphere with a pair of plier handles sticking out the top. You squeeze the handles together to make it work.

I have something like this — I got it for the same reason you mention, the one-handed operation, plus the fact that it has a magnet on it so you can stick it to the fridge — and it turns out not to work very well. Maybe it’s a cheap version of the one you’re talking about, but after a few minutes of frustration I gave up on it. I’d go get my money back except it was like three bucks and not worth the trouble.
Instead:
Ditto here. I enjoy the occasional big spicy bit, which the fine grind doesn’t provide.
Wow, that really, really sucked.
DAMN YOU, you DAMN DIRTY APE!
No, really honey, I’m just trying to be funny and all - just joking. Put the rolling pin down and relax. You’re really not a damn dirty ape. You’re a clean ape - a VERY clean ape - and you’re a cute one at that.
