Improved SAT II for sale ...John

[Brian Trout]

Hi John,

Didn't mean to sound critical in my earlier post.  My apologies if it came
through that way.  It can be frustrating trying to write with expression.
:-)  I understood what you meant.  I probably should have prefaced my
comments so you knew where I was coming from.  Sorry about that.

Just curious, are they using NiCad batteries? or Nickel Metal Hydride?  Do
you know what sizes of cells?  ('C' cells, perhaps?)

Best wishes,
