I decided to go through Amazon and price every card on the list. Here are the ultra-bargains:
ATI Radeon:
X850 - $15 (used)
X1300 - $17 (used)
X300 - $20 (new)
9600 - $20 (used)
The NVidia cards were too crossreferenced and such and were hard to track down. Besides, I've had ATI cards in the past and they worked fine, so one of the above should do.
Any thoughts, gentlemen?
