Personally speaking, if I were spending $200+/- per quilt that I made, and I had the room to have the long arm, I would do it. As far as "how do you know if you'll like it", and "how do you know you'll be any good at it", you won't know until you try, but I think you would love it. I just wish I had the money and the space for one. Oh well, hopefully soon. Good luck and please keep us informed.
