I took a machine in there for repair...just a tune up.  Guess What? It was 4 weeks later and the guy told me he wasnt sure how to fix it.  I informed him it was working fine when i brought it to him and he said well i must be mistaken.  He charged me 85 dollars and now it doesnt work.  I think i will take my business elsewhere and find a well trained sewing machine repairman.
