it is a good idea to visit dealers and shows and try out all of them you can find- then decide what you want- there are so many and each of us is different- and like different aspects of our machines- if you are going to put out all the $$ to buy a new one you want the one YOU LOVE--not the one i love.
try them out- it's like buying a car- there are lemons- there are ones that do this-and others that do that-
the only thing i really keep in mind is customer support- and classes- the fancy-expensive machine dealers give free owners classes to teach you to learn all those great new features- it is nice to be able to take advantage of that service- it's sad to spend $5000 on a new machine then only straight stitch with it because you have no idea how to do everything it does.
