Mine is a Baby Lock Jane that I bought to put on a frame and also got a stitch regulator for it.
That is the only reason to buy a strait stitch machine.
It is very premative with treading, too complicated for me and I dont like the under the machine bobbin I prefer a drop in.
I have a computerized Viking for the rest of my quilting and love it.
My first machine was a Brother quilting machine that only cost $129 and it came with a walking foot and extension table, so you can get a basic quilting machine at a low cost. I still use it when my Viking is in for servicing. Its a great back up machine.
