I have a Rocketeer. I believe it's a 503. I've used it a lot and it's a very nice machine. It has cams for decorative stitches (I've never used mine) but it has a built in zig zag. I pieced the king sized quilt I made for our bed on it and also one of my other quilts. My husband bought mine on ebay for considerably more than $100. I'm sure. But as I said it has all the cams and accessories. It doesn't have the original manual, but the seller had a copy of one that he included. The machine I have was in excellent condition when it came to me. Even my old sewing machine repair guy commented on that when I took the machine to him to replace the light bulb that burned out and I couldn't get it out of the socket.
