Welcome from Mississippi!
I have about a dozen vintage machines but my main quilter is a new(ish) Juki 2010Q. It's very simple, only does straight stitch, but has a thread cutter in the foot pedal, auto needle down stop, and a large harp space. Quilts like a dream. They are under $1000, not computerized, all metal housing. Just what I need.
Before that one I used my Bernina Record 830 from the 1970's. Still using that wonderful machine for zig zag and a few fancy sts.
