My machine tech. has lots of experience with f. weights, and also works on them. He has done a great job with mine, and several friends in guild.
He does work helping people find a machine. He is very trustworthy, and won't rip you off.
I know SE Ks. is a fair distance from Indiana, but just an idea for you if you don't fine one closer.
I got mine at a flea market. Had not been used very much, was reconditioned and ready to go, and sews like a dream. I know the price ranges and the price seems to come and go with the demand. I paid $500 for mine, about 2005. At that time, lots of people wanted one to take on trips to S. Florida, Texas, ect, for spending the Winters. Haven't heard as much about that lately, so maybe the demand is down right now.
If you want my tech's info, let me know.
