  A GAL programmer isn't difficult at all.  High-end, currently  
supported professional programmers (big Data I/O units come to  
mind...I recently replaced my 2900 with a UniSite) are easy to come  
by on eBay these days for not a lot of money.  Well worth it if you  
do a lot of this sort of work.

  Aside from that, it can be done on a shoestring budget with this  
near-trivial homebrew GAL programmer:
