Here's the first two CPLD breakout boards. The designs are on the wiki. I'll build them up now.

I've tried to work with the CPLDs, but a development board is so expensive. I hope they are less expensive and can get one of them.

The should be available soon, (3-6 weeks). You will need an external programmer (like the Bus Blaster) to program them, but they are very inexpensive, hopefully around $5-$10, but I don't yet have a quote. The chips used are only $2 in 1s, so it should be reasonable.

I don't know whether to say "Awesome!" or "Excellent."

May I suggest a kit with a board + the bus blaster for beginners like me?

The bus blaster v2 has a coolrunner cpld as the buffer. It is connected to the second jtag port on the ft2232 and can be programmed without external stuff, so it is a mini cpld dev board. The extra pins are at a header, and the v2.1 will have a button and led too. The breakout is a bigger version of the cpld, so try it out and then implement it on a the breakout.
