Hybrid Tuner for Vista, PCIe, ASUS P5B-Dlx

I'd like to use media center in Vista but my old ATi TV Wonder Pro isn't supported in MCE or Vista.

Ideally I'd also like a hybrid card that can do ATSC HDTV and NTSC tuning. Digital cable would be nice but is optional. FM also nice but optional.

I have some limitations with my setup: ASUS P5B which is native PCIe so PCI is done using an external bridge chip (adding latency). This alone makes me want to use PCIe whenever possible, but the other reason to use PCIe is because I have a SCSI controller on the PCI bus with my OS hard drive on it. The hard drive can already saturate the 100MB/S real bandwidth of that bus. I imagine watching HDTV would be pretty intense on that PCI bus and might cause capture problems. So I think PCIe would be the better choice for me.

So what Hybrid HDTV, Cable, PCIe, Vista ready tuners are out there?
Looks like this might be the only one:

Is it any good?
Hauppage HDV-1600 looks nice and is affordable but its PCI.
