A few weeks ago I posted about my drive for the "X" axis on my BP that
died. I ended up only replacing the circuit board for $107 and the boot
on the full speed switch for $6. The motor had no smell so I started
with just the board. The upgrade board is for a model 150 from my model
100. It works much smoother with finer speed control. This unit is
just a much better unit than the imports! I win!

Tom, awesome job, truly in the old style of American ingenuity. Where
did you get the circuit board?
