IDE Fix Express will work as it's from the same man (Mr Jens) and I'm looking for one myself
I hope he starts making some new ones soon! Can someone say 'SATA'
Anyway, until then the IDE Express is our best bet (FAST ATA is a pain in the butt to get working properly).
BTW Have you tried SpeedyIDE yet? Or how about Cosmos scsi v43.46
