I just had my 1500 in the shop and it was about three weeks getting it back. It locked, wouldn't turn at all. The repair guy said it was the hook, he replaced it. I guess in the bobbin area. Then when he got it all back together and sewing the thread cutter stopped working. He had to fix that then the new spring on the reverse lever he put on popped off. He had to take it back apart to get to that. My total bill was $229. But the machine seems to sew fine. I am leery about the stitches looking a little off but I can't say for sure, probably not. But a machine once repaired seems to go down hill from what it once was.
