For the amount of times your planning on using it, I would try to take a look at the Veronas -- I bought one several years ago, shoot trap every week thru the summer. No problems. A couple guys at my club were both Master gunsmiths who worked at a Perrazi shop locally checked it out when I first got it & told me that it looked really well made & would probably be good for the rest of my life - or 200 - 300 k rounds. Save you quite a few bucks, too.
