ATI has a lot of nice features, I know I have it...crappy driver support as always with ATI...
I run it in win98, but I have heard it lacks support or good support in win2k...so beware. I think it still runing aroun 60 bucks but can be picked up in the for/sale forums for around 45-50 usually...
cheapest has to be hauppage wintv usually sub 40's, but lack all the features of ATI...
ATI has a TV wonder VE version which I believe lacks a few of the capture features and runs about 20 bucks cheaper...
