Great movie and some wonderful props.
2 of the best ones are the holowatch and the modified mini uzi.
I am currently drawing up a blueprint for the addon parts for the microuzi, most likely going to build those up the same way i did the Orbo pistol from Witch Hunter Robin (layers of plastic).
The holowatch was made by Ed Kline, it is a very well made prop. I spoke to Ed about it and he is looking in his archives to see if he has additional pictures and info on it for me, when i have more info, i am going to draw it up in Rhino3D and see if i can have it machined out of aluminium. Ed is a true aluminium wizard and made some amazing props. His total recall work and other props he did can be seen on his site:

The movie also had a Mac 10 or 11 with just a addon piece put in front of the barrel, Michael Ironsode was carrying one of those.
And the gun we also see in planet of the apes (burton's version) was in there, forgot what the gun's make and model was.
There isn't too much out there for sale. Moviebits has some set pieces and mars money and screenused.com has a package which has 2 pieces of wardrobe and an incomplete uzi (missing the rear piece). I asked them if they would be willing to sell the uzi seprately, but they didn't want to and $6000 for the clothes and gun is too rich for my blood.
