A lot is 100 or more

I guess I didn't make it clear that I wanted something that would let 
me program TQFP chips by either removing them from the "racks" they 
come in and inserting them into a zero insertion force (ZIF) "carrier" 
that would itself be connected to something like an STK500.

Soldering anything to the unprogrammed TQFP chips isn't an option.

What we do now is hold the chip by hand onto a proto PCB that we have. 
This is hardly a reliable solution, and is more time consuming than 
necessary.

Another solution is to have a "socket" that is slotted into the 
individual carrier the chips come in. Given enough time I'm sure I 
could engineer a one-off solution, but time is not on my side at the 
moment.

These people ..

   http://www.yamaichi.com/

seem to have solutions but their web site is so badly organised, and 
their engineering drawings so bad, that I'm not sure what they really 
sell, but some other people who make socket adapters use Yamaichi parts.
