WTB: MicroVax II Scsi

My old uVax II (in BA23 case) has been sitting around idle for too long and it's time to revive it or let it move on. Right now it's got a TK50 or TK70 which works (can boot the diagnostic tape) and a flake RD5x drive. After laughing at the prices the gougers on ebay want for those drives, maybe it's time to shift gears and just go SCSI. I think the qbus scsi card is the KZQSA, or are there others that will work? Will the uVax just recognize the card and any scsi drive attached to it, or will there be more configuration involved (particular slots, firmware changes, etc?) Anyone got one for sale? Alternately, if I stay with the MFM controller I have now, will any old MFM drive work, or must it be DEC branded (custom ROM on the drive, maybe?) Thanks in advance -j
