I'm very happy with my Polycom USB mic. There may be better options out now (it's been a bit), and I don't think there's a lot of non-windows support, but I like it. Also, my spyderwrench is awesome, although it doesn't have a dedicated bottle opener. The channel lock pliers work great, though.

When my friends and I (in Michigan) were playing with someone remote (in Minnesota) we gave up on computer mics and went with a phone call and speaker phones. It worked great, but then there was the added cost of the phone call.

I should add that this was about 6 or 7 years ago.

I don't know mics... but after previous experiences... keep the receipt?

Also... maybe try a sound store, rather than a computer shop? Somewhere where a musician might grab a mic? I dunno. Might be way too expensive, though.

Actually, Rockband mics (and games with similar setups) seem to work fairly well and can probably be had for a reasonable price. They use a USB connector.

mutitools: Gerber or Leatherman are the two that pretty much every theatre technician I know has on or the other. (I have a Gerber) Any decent multitool has a good blade, pliers, and a screwdriver, at the minimum. Also, make sure that any one you get locks the various tools when open (both Gerber & Leatherman do). Most have wire-cutters, and I've always found the can-opener & bottle opener useful as well.

On a Gerber you can snap open the pliers one-handed. The knife and tools are accessed from the inside of the handle. Leatherman you can flip out your knife one-handed, the tools are accessed from the outside. (although I think both brands have come out with lots of new models, so that may be different on some models)
