non-DEC-compat HW to read RX02's?

What non-DEC-compatible stuff out there can read RX02's? Obviously the original RX02 drive can read RX02's... as can all the DSD, Sigma, etc. Q-bus, Unibus, Omnibus compatible controllers. But what can read RX02's using a generic SA801-type drive and a PC-clone? Several years back I built a doohickey that plugged into a PC's parallel port and allowed me to step floppy drives and read bit-timing-information, a track at a time, into a RAM buffer, which I then dumped into the parallel port and wrote some software to analyze arbitrary disk formats. I wired the index/sector hole detector to the MSB RAM line and used it with great success to analyze and read several 8" and 5.25" hard-sector floppy formats and eventually pumped a few thousand disks through the scheme. Not bad for something thrown together on a solderless breadboard using random TTL chips I had lying around the basement :-). Obviously similar devices have been discussed here in the past decade or two. Is there anything available off the shelf that can plug into a USB port and let me do similar? Right now the thought of traveling with a 8" HH floppy drive and a laptop has a certain appeal as opposed to hauling around a BA23 and a DSD440 :-). Tim.
