So, why are they so expensive then?

cheap??
You might get an old EPROM programmer at a Radio rally/hamfest. But
they're often not that cheap. How about buildign one for your next
project - to program standard EPROMs (2764s - 27512s, say) is not that
hard. Basically you have to set up the address and data, take one of
the
pins (Vpp) up to 12.5V (or 21V, or even 25V on older
devices) and then
apply a 50ms program pulse to another pin. And repeat for all the
locations you want to program.
When i built my first embedded control system I had to build an EPROM
programmer first....
