In-system-programming is worth considering, but for boards with
sockets it actually just creates extra work. In any case $30 for
flash programming in the tester hardware is way unacceptable. I'm
thinking that $10 is already nearly too high cost, but on the other
hand it buys a very nice ARM7 with USB, which could be reused also
independently of the tester.

This is the question. Anything socketed is easy, but soldered down
chips make it more difficult. For SO-8 I've only seen the IC-CLIP by
Pomona, which doesn't attach with a very sturdy connection to chips. :\
