When I first started quilting, I thought I should upgrade from my old machine. Imagine my surprise, while taking a beginner quilting class, my old machine sewed great 1/4 inch seams immediately and the other students (with fancier machines) were constantly struggling with tension, feet, and their 1/4 inch seams. I realized my old machine was a good machine!
I'm still happy with my old machine. Maybe in the future, I will get a fancier machine but right at the moment my old machine is still working for me. Unless your current machine is not running well, take your time with an upgrade decision. You will have a better idea of what you want, which features you would use, and which features you wouldn't.
