At a guess: one market for them would be people who want/need to
program certain legacy PIC chips that require a parallel interface and
(I think) a relatively high programming voltage.

The modern PIC chips use a "very few pins" serial programming
interface, and the modern batch of inexpensive chip programmers often
do not implement the parallal programming algorithm for PIC.

Another option, of course, would be to disassemble the code for the
older PICs, and port it to a modern PIC chip.  However, I suspect that
this may well be a non-trivial task in many cases - the chip pinouts
and the peripheral sets are different enough to require significant
re-engineering.

So, for people who are repairing older hardware that uses the legacy
PIC chips, or building "clones" of these devices, it may simply be
cheapest and least-hassle to buy a tube of the old parts, and an old
Picstart.
