Flashed Radeon 9800 Pro died. Anywhere I can find a cheap X800XT?

It seems that everytime I throw in an ATI Radeon 9800 Pro (AGP) that's flashed into my G5 DP 1.8 June 2004 PowerMac, it chews through it within a year or two, ending up killing the card with the infamous vertical lines in random areas of the screen.

I have had moderate success in keeping my last card afloat with an aftermarket fan, however it finally gave in today, when the card completely shorted.

I'm running on a spare Radeon 9800 Pro (flashed) which has the same configuration as the card that died, except this has a lower core GPU and memory clock speed.

I've been frantically searching for a cheap replacement (under $120) for a Mac edition Radeon X800XT 256MB AGP card, but only came up disappointed when I saw the few (and quite expensive) results on ebay, as I can't use paypal (can't verify my address since I don't use my bank often) so my only options are left to searching locally or going on amazon.

I do want to save my Mac, it is a beast of a machine, I love it to death, and I simply want the best for it.
