Brand New, these are not surplus or RFE
$50.00 ea.
I've checked my steppers and there is some 'stickion'. The clicks also
don't all appear to offer the same resistance, some feel soft and others
offer more resistance. I prefer to start with a quality motor and not have
to worry about it being the cause of problems.
Local shops either have the same crap I have on hand (which is where I got
them in the first place), or are outrageously priced and don't have 3 of the
same model on hand (ain't no way I'm mixing up the motors, I want 3
identical ones)
