I've owned a Dataman S4 going on nine years now, but it's really
starting to show its age device/feature support wise and I couldn't
recommend it to anyone that is buying new.  The unit doesn't play too
well with USB to serial adapters in my experience, and doesn't support a
lot of the newer flash devices (especially faster 37VFxxx parts). 

Dataman does have some newer devices like the 40Pro and 48Pro that
support USB natively but you don't get emulation.  With flash parts I
don't see emulation as a big deal as they're lightning fast to program
and you can just plug a ZIF socket into the target device for easy
swapping.

For reading 2708s I have a wirewrap socket with a couple legs bent out
and connected to standard PC power supply with a junk hard drive
attached for a load.  Who really wants to reprogram and put a 25-30 year
old 2708 back in a synth anyway?  Not me.
