Great topic. I just bought a 7550 from a friend for $300 and it came with a table/desk and all the extras. I bought it because I also wanted the IDT. Just got it set up but have not had the chance to use it but I am looking forward to sewing with it. I know she took very good care of her machines. She had to replace the mother board a few years back and I was wondering why that would go bad and if that is very common? Has anyone else had this experience? Good luck with your decision.
