Ok, a s.e.design thread has got me thinking about pan-frying BGAs. Now I'm curious. What's a good BGA to start with? "Good" is defined as: 1. Inexpensive, cause I'll probably toast a few. 2. Useful, because it's good to see results. 3. Easy to design around, because I want to worry about the soldering process, and not burn through a number of chips getting the design 4. Require a minimum of support components. 5. Not so complex that lots of tiny vias would be needed. If I can get by with two rows pulled out on the top with 7/7 rules, and the remaining rows tied to gnd/vcc through one or two big vias, that's acceptable.
You could try some DC-DC chips like the ON-Semi NCP1523, 8 pins and only five or six passives. TI or National may have others.
