The SuperNova is a high shank machine, which is a little more adept for quilting and will take industrial feet. The feed dogs drop so you can free motion. There's three set needle positions, but you can often sneak in five. The harp isn't the largest in vintage machines, but it's not the smallest. It takes normal needles, class 15 bobbins... upper tension dial has twice the threads as most machines of it's day so you can really dial it in. There's even an indicator for presser foot pressure. They make l-e-d replacement lamps... you can still buy belts, and just like most any other vintage machine, you do have to oil it on occasion and read the instruction manual. Plus, it does a crazy bunch of deco stitches and there are several user groups online. 100usd is a fair price if it's up and running with no issues. To be safe-r, the seller should know the machine, have used the machine, and be able to tell you about it.
