GeForce 3 sources?

[Kenneth Strain]

OK, so I can see that the easiest card to install and have success with is a
Geforce 3.  How can I find one that will work specifically for the Mac?  On
eBay, it is very confusing, there are so many versions.  I am not a gamer, I
simply want something that will work with the 20" monitor down the road, and
take advantage of Jaguar.  And be easy to install!  Any pointers, or cards
that someone want to get rid of, would be appreciated.
