I have a NewStyle 228 that was used about 5 times prior to it coming to me. I have never used it, but will attempt learning once I take it in for a check up. I got it over a year ago for my favorite price...free. It does run and was in a friend of mine's family. The mother used it 5 times and then the father died. Since he bought the machine for her, she couldn't face using it. The mother wanted someone to have it that would love it, and so I inherited a machine.
Being new to quilting and never long-armed, it can be intimidating. Luckily my LQS will come to my house and give me private tutoring for cheap.
Maybe time will tell what you need to do with your machine. I hope you decide to keep it and maybe get some lessons.
