The staff of Moses from The Ten Comandments.
Ray Harryhausen’s Rhedosaurus, Willis O’Brien’s King Kong
The Time Machine, from the 60’s.
The Orgasmotron. I figure I can hold onto this and trade you the rest of your stuff for turns.
Also…
Radio Raheem’s ‘Love’ and ‘Hate’ knuckle rings.
Bruce Lee’s nunchanku.
Stan’s hat.
The entire War Room from Dr. Strangelove.
The Auryn, and the NeverEnding Story book.
The Bat-a-rang.
The Glaive.
Billy Baroo.
And although obviously not as tempting as the original, “Bad Motherfucker” wallets can be had on eBay.
The Millenium Falcon.
Ash’s boom-stick and chainsaw.
A flashy-thingie. “Did you flashy-thingie me?” “No.”
Darth Vader’s helmet.
My tastes are simple:
the plastic bag from American Beauty
or the coffee can from The Big Lebowski
or Dirty Harry’s gun if I want something heavier.
I always fancied having my own Hannibal Twin-8.
Push the button Max!
I want one too!!!
The prop that immediately came to my mind upon opening this thread:
Buck “Uncle Buck” Russell’s bowling ball.
Why not the skull bowling ball from Mystery Men?
As for the pulse rifles, a similar real-life rifle exists; the Objective Individual Combat Weapon (aka the M-29), coming soon to a war near you.
I’ll pass, thanks. The OICW is an overly large, heavy, cumbersome thing that requires you to carry more battery than ammo. The Pulse Rifle is a relatively svelte work of art that makes the coolest goddamned sound in the world.
I guess if I carried an OICW and an boombox for audio reproduction, it would be passable…
Why thank you for passing up and thus allowing me to claim K-9 Mk. 2. 
I’ll also take the nifty softball bat that Ace had for a bit in “Remembrance of the Daleks.” Actually, in case that bat should break, I’ll take the Hand of Omega as well, so I can easily craft replacements.
The sandman’s Weapon from Logan’s Run. Not your stereotypical ray-gun. The effect was not added in post-production. The actor’s prop actually shot real flames. (OK, it was basically an oversized cigarette lighter, but it looked really cool.)
Thought about it, but as cute as he is…in all honesty, without John Leeson’s voice behind him, I kind of felt like he’d seem just a little bit lame close-up and in person, what with the wobbly aluminium skirt and all. I’m glad he has a good home though…and I should probably take this opportunity to reserve first dibs for whatever sleeker, more agile version they may come up with for the new series.
:smack: And criminy, no one has spoken up for a genuine Fourth Doctor scarf yet?! Throw that bad boy in Bessie’s boot along with a Sea Devil flame gun and drive me to anorak heaven.
From Aliens, the loader (forklift?).
Hittori Hanzo Swords.
The homing device in Total Recall and the device used for removing it.
Oh, man, the Landmaster from “Damnation Alley.”
AWESOME.
Creates diversion
Quietly collects Ring of Rassilon, Raston Warrior Robot suit, and The Master’s chess-like statuettes before those other jerks can get them.
Breaks other Doctor Who props
A bit large for a prop, but years ago the Franklin Institute in Phila. had the queen alien from Aliens on display. Holy crap, I want one.
The ultimate prop for me would be Han Solo in carbonite to hang on my wall. I think Sharper Image had one for about six grand. (Boba did all that work for six grand??)
