Read all these posts, and most of you have different machines. I have an older Bernina that is a workhorse believe me. I forget to oil it, I forget to clean it or even take it in, it doesn't care it just keeps on working. I have had this one since 1981, and have sewn things like canvas boat tops, tents you name it. I know you don't have to have a machine that will do all that to quilt, but that is only an example of my machine. It just keeps on working.. Ok now that I have bragged about my machine...
Here is what I would do if I had a set budget and was looking for a machine. Go to some of the dealers you would like to try, and ask about used machines. Try out some of them in the shop. I am sure if they think they have a sale, they will help you in any way. If not you don't want that machine anyway. You want someone that is a responsible dealer and stands by thier machine, new or used. Ok this is long, and probably stupid, but its a start.
