Are you only looking for a computerized long arm machine? That is expensive. I use a normal size machine on a 12' quilt frame. My quilting area is limited to approx. 5" but that's okay. I recently ordered 'grooved boards' and a stylus to try quilting with them to guide me so I can do more than meander. There are many ways to accomplish what you want. Try different machines wherever you can find one to try.
