WTB: G4 PCI upgrade card for PowerCenter Pro

[livingfortoday]

Hey all, I'm looking for a Sonnet Crescendo PCI G4 card or similar (can be other brand) to upgrade my PowerCenter Pro. It's currently running an XLR8 480Mhz G3, and it flies through OS 9 on that - but I want OS X on there too!

So if you have something reasonably priced that works, let me know. Keep in mind that the 1Ghz G4 from Sonnet is a smidge under $100 on OWC, so unless you have something like that, don't go quoting me the moon.

Thanks!

I should add that I'm up for trading the G3 card towards a G4 with some cash as well. Sinc ei really won't have any use for it once the computer is upgraded.
