usb microphone

i'm trying to lighten up my setup as much as possible, as i am leaving the country soon and will basicly be living out of my backpack. although i like my shure mic and soundcard, both those and the mic chord all together weigh alot, well not ALOT, but that shit adds up when you're carrying it around for miles at a time.

so i'm going to have my laptop, skip my soundcard, and just use my controller keyboard (i can use with just usb), and i recently got the new akai lpd8(awesome) - so all that is left is to get a usb mic to complete my on-the-go setup.

have any of you guys used a usb mic that you like? i'd like to keep it under $100

from what i read, the Blue Snowball USB Microphone is good:
