The Avante 18 by HandiQuilter starts at around $6,800.00. Gammill is $30,000 - $40,000. That's with most of the bells & whistles, including the Stadtler Stitcher. The Avante 18 comes with the stitch regulators standard, but the Pro Stitch is another $9,000. I'm not interested in having a machine that's smarter than I am! :) I am also afraid that if I wouldn't get the quilt perfectly square on the rails, the computer isn't capable of compensating for my error.
I'm saving for the Avante 18. Am going to add on the Micro handles. They're available as an option. Haven't talked about any other options, yet.
