While at the quilt show, check out the Innova booth. Their machines are easy to self maintain and only a phone call away if you run into trouble. My dealer is in the next state so a distance. Any time I've had an issue, usually operator error, I've only had to put in a call to Michael and he has walked me thru. As I have the upgraded tension system, no oiling the felt pads and just need to add a drop or two of oil between bobbin changes and cleaning out the bobbin area during the bobbin changes. Other than that I haven't had much problems. I did have one issue though which took a while to figure out what the problem was and who was responsible in repairing/replacing it but ABM/Innova came thru like a champ and replaced the part. No trouble since then. I've had my machine since 2012 with a 3rd party robotic system. I love my machine system.
