Why settle for a $20 first-gen phaser that only looks cool, when you can build your own fully-functional Blu-Ray Laser Phaser for just $100?!

A collection of other functional replicas after the jump…

You could spend $30 on a communicator that belts out phrases from the classic series like “Enterprise, this is Kirk” or “Your signal is very weak; can you turn up your gain?” …OR, you could turn up your gain considerably with a USB VoIP/Skype phone built into the same hardware.

There are dozens of replica kits for building your own Klingon Disruptor. The one above costs $68, which seems reasonable. Then again it’s only a resin prop gun that “cannot be made to fire anything.” Boooo!

Hands down the coolest replica I’ve ever heard of is this homemade disruptor constructed from a parabolic reflector, a horn antenna, two ignition coils, and a car battery. No pics unfortunately, but here’s the particulars: 1) it cost $500 to build using off-the-shelf parts; 2) it fires off a 20 megawatt burst of radio that can disrupt or burnout virtually any electronic device from a distance of 20 feet; 3) It makes the TV-B-Gone look like child’s play. Just imagine what carnage could be inflicted at CES with this disruptor.

Tribbles sure are cute. But beware! Not all tribbles replicas are not created equal. These ones from etsy are handmade, but on the inside, all they are is Polyfil. Instead of buying a dustbunny that just sits there, go for a battery-operated tribble that shakes and quails [$15-20 via ThinkGeek]. Better yet, build your own (above, via Instructables). Warning: soldering required.

OK, maybe this Red Shirt cologne wasn’t official UFP issue. But, if you’re going to suit up in the storied red shirt, you should probably care less about recreating the “smell” and, instead, deck yourself out in as much high-tech riot gear as possible…
