I'd also like to find a supply of inexpensive
MicroSD cards smaller
than 4GB. The best I found from a few minutes of trolling eBay was
lots of 10 and 25 for around $2-3 each for 128MB or 256MB. I'd rather
find a lot of 25-50 for $1-$2 each. I certainly don't need to go out
and get a stack of 4GB MicroSD for $5-$6 retail if I'm not going to
use 90% of the capacity.
How hard would be be for these SCSI to SD adapters to behave as if
they were several drives, thereby giving you a chance to use all
of that capacity?
At those prices, though, it's hard to quibble.

SCSI is SCSI, right? I kid, I kid.

In terms of supporting multiple SCSI LUNs, it's down to what the
target host can do. For some, it's just a regular part of doing
business. For others, they expect embedded SCSI devices to be one
SCSI target == one storage device.
Back when SCSI-MFM and SCSI-ESDI bridges were common, people cared
about SCSI LUN support. Once embedded SCSI took over, interest
rapidly waned.
So the protocol supports it, it shouldn't be hard to have the SCSI2HD
firmware support it, but it would only matter if your host also
supported it.

It would be somewhat easier to just pretend to be multiple
SCSI IDs instead of a multi-LUN device. That would
also enjoy higher support among hosts.

It seems to me that you could have the SCSI2SD respond as multiple targets, all on
LUN 0, and avoid any LUN issues. That would give you 7 drives to play with, at least...
