The PCI catweasel seems like a great card let down by a lack of software and emulator support.
Still, it seemed worth getting the flipper version because you had the potential of getting sid support + all the other features both on the PC and Amiga. Now that it is non-flipper it is much harder to justify buying.
Perhaps if the zorro 2 version was improved to have a sid option or a ps2 port it would be a more compelling buy.
