I have the HQ. Granted it is the 16 and was used. But I was able to affordably upgrade to the ProStitcher. The reps here gave me free instructions. I also attended Quilt Camp http:www.quiltcamp.com where i took HQ classes as well as other quilt classes.
HQ has wonderful support, free videos, and are available by phone to walk you through any questions or problems.
If I got another machine it would have to have the computerized portion. The PS includes a QuiltCAD program which is wonderful.
