  Don't know if you got any takers or not, but I'd be up for this on some
weekend that wasn't Easter.  I can give you up to 1kw of modified sine wave
AC from an inverter, or 4.5kw if I throw the generator in the back of the
pickup.

  Now that I think about it, I'm out next weekend, too (for work).  Jobs
sure interfere a lot with hobbies...
