If you get one you will be even more hooked. I fell in love the minute I used one at a show also, then oh my, I got a HQ16 (yes not as big as some of those at shows) but true heaven, sure beats sitting with the quilt over my shoulder and feeding it through that throat of the machine. Good luck on your research, if you haven't yet, check out yahoo groups on the machines that interest you, try many, go to shops that have them, test drive as many as you can. They are an investment and get what you want and can afford the first time.
Enjoy your research.
