Dan, thanks for the advice. I had already read the thread you had linked. So much info to absorb. There are a couple machines locally around here on CL. The one I was interested in is a Consew 226 walking foot needle feed machine. It has a clutch, no servo, darn. Oh well, I could learn on it making a new boat cover. Maybe then I could loosen up the purse strings and buy a servo motor.
