I don't generally just jump up and defend myself, this time i will.

What i was THINKING of, if a vfd had no signifgant advange on price
point, was to buy the electronics for a ROTORY and buying the motor
locally.. This saves, oh, a hundred or 2 in shipping. I believe the
context of my posts relayed that to everyone.

sorry for the nasty reply, as I am no newbie to internet forums, just
this one.
