I have an ATI TV Wonder 650, which is pretty much an ATI TV Wonder Pro, and I'm selling it for $50. I paid $110 for it at Best Buy and I've hardly ever used it.
Here's a clip I capped with it:
Mythica.org: wtf_not_overkill.wmv
and that's nothing really compared to what it could do if you use one of the millions of tuts out there; I did that real quick to show a friend in RL.
If I can't sell it here I'm going to put it on eBay, but I'd rather sell it to someone in the Halo community first.

IM me at i am b1g if you have any questions.
