Tomenosuke Blaster Pro
If you're a techie geek or a film buff, you've probably seen the Tomenosuke Blaster (from Tomenosuke). It's a Japanese made prop replica (without the Blade Runner licensing) that's extremely complex and high priced (84,000 JPY or around $1,050). But man! Does it look exactly like Rick Deckard's firearm.
They've already sold out of several version of the replica blaster - about 900 total pieces. Now, Tomenosuke is selling the third edition, which is an edition size 300 pieces...and as you can see from the photo gallery below, the most detailed model yet.
