You can buy a used Pfaff for about $400, depending on which machine you get. They are great machines because they have dual feed dogs (one for top fabric, too) built in, which helps the top fabric to move at the same rate as the bottom fabric. This helps you match your points easier because fabrics which start out the same size end up the same size at the end of the seam. It acts like a built in walking foot, one which can be used with many specialty feet, as well as the piecing feet. Watch your local Craigslist and ebay. I would also suggest contacting local quilt guilds. Often times members may have an unused machine to sell. Be aware that some of the really older Pfaffs don't have dual feed dogs---they are usually called IDT, so make sure the machines you consider have them. If there are pictures, it looks like a slender black angled piece directly behind the presser foot, and it fits into a groove underneath the presser feet. Good luck, and have fun shopping!
