Whatever you get, make sure there is a dealer in town. In fact, buy from the dealer if you can. I get bumped to the top of the pile when I take my machine in....because I bought from her. How do I know this? My sister didn't buy from her, and I took my machine in the day after she did. I got mine back the next day, my sister waited 3 weeks. I bought a demonstrator and am very happy with it.
Also be sure to try out the machine. In fact, take something you are working on with you. I hope you enjoy the hunt!!
