WTD -- ST506 style (MFM or RLL) hard drive and controller

Hi guys, I'm toying with the idea of doing an MFM/RLL hard drive bolt-on for the DiscFerret (seeing as the DF hardware is basically done now -- I'm just doing a final design check before I send the PCBs off for manufacturing). Problem is, I don't have a drive to play with. Does anyone have any or all of the following kicking around? - MFM or RLL hard drives. I could do with one or two of these; anything's good, as long as it has an ST506-style interface (that is, straight MFM/RLL with no funny business) and is believed to work. I'm ideally aiming for something "of reputable manufacture" -- so not a Kalok Octagon! - Cable kit for the above. So that's the Data and Control cables -- edge connector to IDC plug. - MFM/RLL controller to match the drive. Anything goes here -- e.g. Western Digital WD100x series, DTC, Omti... as long as I can make it work with the drive for long enough to format the drive and 'dd' some data onto it. I'll even consider SCSI-to-MFM bridges if they can be relatively easily tied to a modern PCI, PCIe or USB SCSI card (say, an AHA2940). I'm happy to pay reasonable market value for the above, but that doesn't extend to paying ?390 for drive-on-its-own (read: drive that's had the PCB removed and is basically useless) on "that online auction site"...
