I have an innova 22 inch with lightning stitch. I bought it in November and it is so fun to use. Innova has great customer service and their machines have very few issues. You get much more machine for the money than you do with a gammill. I test drove just about all the brands, and took classes on both handiquilter and gammill. I preferred the handiquilter over the gamill after my classes, but loved the innova from the first use!
Good luck in choosing! It is a big purchase so make sure you try the machine out before you buy. You might find that you prefer a brand you haven't even considered once you test drive them. All have a steep learning curve, some more then others.
