I haven't committed to owning one just yet but if I do decide I'll be getting this one. The Martelli LaCresta long arm quilting machine. No question about it.
The Martelli LaCresta long arm quilting machine is built to never see the service technician once the machine is installed.

Sorry, it isn't the most inexpensive one. I didn't read the subject right. But boy what a machine!
