I have a Gammill Optima equipped w/a Statler Stitcher that I purchased Oct 2007. I went back & looked at my records. I didn't track it the 1st year but the years I did track it, I did between 90-100 quilts a year. I have only had to have one service call in the entire time that I've owned my machine. Fortunately for me, the Gammill dealer is only about 20 mins from where I live. It's an expensive piece of equipment, but it did pay for itself over time AND it keeps me busy *smiles*.
