What do you really want?
newegg.com's considered a good seller, and oft inexpensive.
The 9600 or better's a superior card versus the 9200 (pretty much a repackaged 8500).
You can modify 9800SEs into 9800 pros, but how well it works comes into question.
I personally like my Geforce 5600XT. Cost 95 dollars, open-box special.
Given an option in the matter, go fanless. The little fans always clog and whine. I've seen 9600SE without a fan and Geforce 5200
