I have a Babylock Serenade which has a start button, speed control bar, knee lift for the presser foot, and needle down. It's around 2 years old, so there could be some out there for sale used. I paid around $1,200 for it new, just to give you an idea of what to expect to pay for a used one. It has a nice big plexiglass table which fits around it, and the harp space is 8.75". If that's not enough harp space for you do free motion quilt in, then I'd look for a used Janome Memory Craft 7700, which has an 11" harp space. Those are also about 3 years old, so you can find a used one out there for sale.
