I have a 930 that I purchased new in 1985 and paid $1,500.00 for it on sale. You got a freebie there. I wish I could find steal on another 930 like that. I think it would definitely be worth taking to your Bernina repairman and have him check it out. I love mine ad have never had any problems with it yet. I wouldn't trade mine for any new or old machine. I have no idea about the issues you are having, sorry I can't help you out there, but I hope you get them resolved and get to enjoy your new machine.
