Agree with the other posters. Sometimes you think you know what you want from reading but once you try them out, it's a different situation entirely.
I had it in my head that I wanted a Handiquilter Avante. I went to a show and tried out everything. If I were ever to get a longarm it would be an Innova - hands down. (Believe it or not, they're pretty price comparable.)
Finally, this is a very personal decision. We can give you leads on machines and tell you what WE think, but ultimately, you have to love how a machine feels and operates in your own hands. I suggest you take your time making the decision.
Good luck.
