I have an 830 which i use mostly for embroidery and love it. I have not had problems with it but there is a learning curve. My BFF has a long arm and is teaching me to use it. I find the space requires a lot more than the 830 but for quilting it is a dream. I would definitely look on Craig's list for either or both before paying full price for new, not being for sure which you want. Good luck!
