PC Transporter, a GS, and a need for HD floppy drives

[hbcsc419@huey.csun.edu]

I have an Apple IIgs, a PC Transporter, and some XT-compatible software
that should work on the PCT. The only problem is that the disks are High
density disks. I know of two ways to get PCT-compatible HD drives running
on the GS, either use a Blue Disk card and some IBM drives, or a Universal
Disk Controller and an Apple Superdrive. The Universal Controllers are no
longer in production, and I don't like the Blue Disk idea. Is there any
other way of getting a HD floppy drive running on my IIgs that the PCT can
read MS-DOS from?

Thank you fir any help you can give,
