Price is an interesting debate ....
But you have to first break the conversation down by action style: Pumps, Semi-Autos, Over Unders and Side by Sides .....then it might mean something.
Pump guns: $ 150 - $ 800 new today. Are the less expensive guns dangerous - No. Will they break or have warranty issues - probably. Will some of the more expensive pump guns have issues - maybe. For me, the best pump gun on the market is Browning BPS hunter model retailing for around $ 500. But picking a gun is also about Fit - not just price. But when you go up in price - you will probably get more durable internal parts, better steel, better quality of machining, better quality chokes.... I have no need or use for a Tactical shotgun / but if I did want one - I'd go to Wilson Combat and order something or a Benelli M-4 (which is a semi-auto).
Semi-autos $ 300 - $ 2,000. Same issues. for me Benelli Super Sport is a good solid gun - retails new for about $ 1,875.
O/U's: $ 500 - $ 1,000 - guns with a lot of problems / $ 1,000 - $3,000 some good long term guns / $ 3k - $5K some upper end quality "Target" grade shotguns / $ 5K - $ 30 K some of the better guns made ( Kolar, Krieghoff, etc ). Personally, Browning XS Skeet with an adjustable comb / parallel comb is a very good overall gun, lots of adjustabilty to fit many shooters - listing for around
$ 3K today ( and its the gun I use for hunting birds, sporting clays and Skeet ).
SXS's same issues
Buy what Fits you first ( so it hits where you look ), buy the action type you like, buy what you can afford, buy what you think is a gun you will enjoy for many years - and you can't really go wrong.
I will also tell you my first shotgun was a 16ga bolt action / when I was about 8 yrs old .... My first "grown up" gun was a Browning BPS 12ga pump - and I used that gun for hunting and for Trap for many years - until I made the choice that I wanted a "long term - Target grade gun" and went to the Browning O/U's ......... so sometimes it takes a few years for things to settle out in your life ( high quality guns are expensive ..).
