gEDA-user: fun/easy BGA part

[DJ Delorie <dj@xxxxxxxxxxx>]

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.

Hmmm... BGA challenge anyone?  ;-)
