An SCSI card that works with tiger?

I have aquired a Sony SDX S500C AIT-2 drive that I wish to use with my quicksilver G4 server. I need an Ultra wide SCSI card that will work with tiger. I thought this wouldn't be a problem, but after picking up the drive for cheap on eBay it now looks really hard to find anything that works with tiger for less than $400. Does anyone have any experience of an SCSI setup that actually works? The Initio Miles 9100UW looks promising, but according to the Dantz site it is not supported by retrospect, but I assume this doesn't necessarily mean that it doesn't work...

Looking forward to hearing your experiences.
