I once had a good Kenmore sewing machine. The tension was off somewhere and I took it in for servicing to the local repair store. They charged $85 just to look at it, not fix it! I didn't know any better and paid over $100.00 for my poor little machine. It did work but I could have bought a new machine for a little more. That was over 10 years ago and I have never gone back.
A few years later, a piece of the feed broke off. I gave the machine to the Salvation Army and bought a Brother from Walmart. I have since learned alot in those years. If any machines need repairs, I will now do what Billy suggested!
And Billy, I live in Kingsport, TN. Would the shipping be expensive to send a machine to you for an overhaul?
