Based on the few I've seen at my local club....they have a spotty record...( and as I recall...they had a number of firing pin issues / and at least one of them was not cycling )...so I can't recommend them.
In terms of shotguns...I think you get what you pay for / and the price of the gun ( compared to cost of targets and shells in a clays gun )...will be the least expensive item in the long run - if you shoot much at all. ( 100 targets on a sporting course and 5 boxes of shells will cost you about $100 )....and even if you only do that 10 times a year, you're at $1,000 ....
In terms of the most reliable semi-autos out there....Beretta, Browning and Winchester have good records on gas guns ...and Benelli on Inertia guns...( and for the most part prices are around $ 800 - $ 2,000 ) depending on what you need.
