So the Firmtek card in my G4 crapped out and I was not paying the $70 for another Firmtek card. I bought a Sonnet TSATA card and I can confirm it is IDENTICAL to the Firmtek, even funning the exact firmware. Just wanted to get that out to anyone who needs one, as they're considerably cheaper than the Firmtek. The Sonnet also has not been discontinued like the Firmtek and still ships with a warranty.
