I've been wanting to get into CPLD programming. What kind of software 
works well, and what would my startup costs be? What can I do for free 
or very cheap? What do I *need* to buy? What are my options, 
software-wise, on Windows XP?

If it isn't, that takes it out of some hobbyists' range. I have enough 
trouble soldering through-hole components. :) although, I imagine, if 
you have the right equipment surface mount can be much easier. Just 
bake to board, with all surface mount components in place, from what 
I've heard. I guess it'd be difficult to do both sides, though, if your 
design calls for it.
