I've had good luck on ebay. I bought a really nice Elna last year for under 150.00. It's a great basic machine. I also bought a Brother machine with more bells and whistles, under 200.00. It has lots more stitches and it's computerized. But, my old standby workhorse is a 38 yr old Kenmore, it still sews great. I'll bet your old machine just needs some further adjusting. Since you are just starting out with your quilting, I wouldn't break the bank on buying a machine. Get something sturdy and easy to use and I think you will be very happy. You can always trade up later on and keep your starter machine as a backup. Most of us have several machines.
