I use my Brother 4000D that I purchased used from a member on here! LOVE that machine! The Laura Ashley Quilter (by brother) is an awesome quilter and is 40% off here in Canada right now. That is ALOT of machine for $1700. You might want to look into that.
Going from one brother machine to another is alot less of a learning curve, and you do get alot of value in a Brother, and very few headaches
