I purchased my Gammill Classic new in 2000. No stitch regulator, no computer. $4000 would be a bargain for these workhourses. I used mine in my business, about 2500 custom quilts completed on it and it is still going strong. In 21 years only had to have service on it twice and one time was my error shortly after purchasing it. With these old machines a phone call can usually fix any problem.
