thanks for the advice guys!
i thought about Radioshack, but wasn't too sure of how the quality of those would be. (they are pretty accessible, and on the cheap side)
I looked up condenser microphones on Amazon & Musician's friend, and there were a lot that weren't too bad(price wise).
I don't really know much about mics (im new to this stuff), so I get pretty confused sometimes...
I did, in my searching, find this:
usb mic
I don't know about the quality of this brand, but it seems like it would fit my needs (which aren't much) perfectly. ^.^
