Where Does He Get Those Wonderful Toys?

Good choices, all. Now here are mine.

Best Ship (large)
Winner: Enterprise NCC-1707-D (ST:TNG)
This baby's got it all: speed, power, excellent recreational facilities, and the best tech in the fleet. Whether you're stopping a Borg invasion or boldly going where no one has gone before, this is the way to go.
Runner Up: Heart of Gold (Hitchhiker's Guide)
If you can do the math, this ship can do anything, including making a really great cup of tea (eventually).

Best Ship (small)
Winner: Millennium Falcon (Star Wars)
She may not look like much, but she's got it where it counts. And it's the only ship to play a significant role in the destruction of both Death Stars.
Runner Up: Serenity (Firefly)
Just the thing for the adventurous entrepreneur: fast, maneuverable, inexpensive to operate, and easy to maintain. A ship like this will be with you 'til the day you die.

Best Weapon (ranged)
Winner: Wookie Bowcaster (Star Wars)
Okay, it hasn't got the fastest rate of fire, but it's accurate and cool-looking!
Runner Up: Battle Staff (Stargate)
Devastatingly effective and easy to operate—just point and shoot.

Best Weapon (hand-to-hand)
Winner: Minbari Fighting Pike (Babylon 5)
Simple, effective, and easily concealed, it's absolutely dazzling in the hands of someone who really knows how to use it.
Runner Up: Lightsaber (Star Wars)
Just this sight of this thing is awe-inspiring. An elegant weapon, from a more civilized time.

Best Tool
Winner: Sonic Screwdriver (Doctor Who)
It comes in handy for bypassing locked doors and other such nuisances. Security override? We don't need no stinking security override.
Runner Up: Tricorder (Star Trek)
We have instruments of the $500,000+ variety in my department that do only the merest fraction of what a tricorder can do. I would have loved to have one for my Analytical Chemistry labs.

Best Exotic Device
Winner: Tardis (Doctor Who)
It's hard for me to imagine something more useful than a functional time machine. Plus, if you're a pack rat, there's an infinite amount of storage space inside.
Runner Up: Alien Healing Device (Babylon 5)
This would be a boon to every hospital around, were it not for the rather unfortunate side effects....
