before you make a decision, take the time to rent some time on a long arm to see if you like it, and be sure to check on internet--google "comparing long arm quilting machines" and you'll find some articles that will give you info. THEN go to a major quilt show and test drive the different machines with a list of features you've decided you want. Sometimes at major shows they sell the machines used in the long arm quilting classes at a significant discount so they don't have to ship them back as do the vendors . once you've figured out your "want" list and budget, you'll know whether you are shopping new or used
Also--while most long armers do stand a lot (loading, doing pantos, etc) consider adding saddle or drafting stool in the future if you plan to do much free hand quilting and choose your frame/table accordingly--glad I did!
