I know quite a few of us own and use these. They're no longer being made. The 20/28ga head on mine developed a problem. Contacted them and was told to send it in, that they had repair parts. I did, enclosing a check for $25 to cover repair and shipping, and a note to let me know if that covered everything. (When I asked how much it would be, he said just cover postage!)

Well, about a week after sending it, I got it back today. Cost about $7 to send it priority mail, and the package included a $10 bill as a refund! Don't know how long the parts inventory will last, but good to know we can still get them fixed.
