These guys are pretty reliable in customer service. (This is not an official endorsement; the .Org has no ties to any manufacturer or vendor). Note that the 256MB cards cost up to $400, where the 128MB cards - which will serve you quite well), are under $100.

Or type in "128MB video card" in our Goggle box above, click "WWW", then enter; that will give you many vendors to choose from.
