if your video camera is analog - all you need to get is a Geforce 4 ti4200 video card with VIVO feature (Video in, video out) inexpensive relatively speaking, and will digitise anything you put into it, good for games too
ah i just asked my brother, he said it was 300 when it first came out. now its like 125 in seattle where he lives. but i live in alaska so its prolly more
Look on ebay. I build computers and built this one I am on now. You can get brand new stuff dirt cheep on ebay. Just do a search for ti4200 and see what you can find.
Or try pricewatch.com they have awesome prices on comp parts too.
