I can almost guarantee you 100% you will love it. I have just a very basic short arm that I am over the moonwith. I wasn't sure I would be able to do much with it but I am so glad I got it, now I want to upgrade to a bigger one but that is beyond our budget right now. Its a someday thing.
Don't hesitate at all. I don't have all the answers and know nothing about your setup you are wanting to get but I would certainly be willing to help you out if you get stuck on something... also there is a yahoo group for almost every brand on the market and several others that are just for general machine quilting and those ladies and gentlemen are always ready to help us newbies with questions or problems. I have made a very nice friend who I now email privately when I have any trouble. They are just a great bunch of people.
