I also recommend a Singer 31-15, or 31-20. They can be found for cheap sometimes, about $150 around here in Central NY. At that price you will have to do a lot of cleaning, but should end up with a useful quilting machine. If you find one without the table and motor, know that you can buy new ones for a few hundred dollars, $300-$400, if I recall correctly. I am not sure how big the throat is on this machine, 10-11" I think. 12"-15' will be near impossible to find in an older machine, IMHO
