Are you looking for a gun that you will hunt with and keep forever or a possible occasional use and resell down the road?
If your not looking for something collectible that will likely increase with time, then I agree on the small bore beretta. I love the 410 I got but agree with some of the above comments that the fit is just not right on the bigger bore. Great fun for under 2k.
I recently found a 70s model ted label 20 ha for my wife at an auction for under $1000 and it's a great gun.
If you are looking for something to put $$ into that will appreciate, then take a look at some of these. http://jamesdjulia.com/auction/october-2015-firearms-auction/?session=2
Their value is heavily impacted by who the engraver is as "artwork". Generally, the smaller the bore-the more desirable and $$ they cost.
What I love about the old fn b-25's and browning superposed is that they are unique pieces of history and not just a production. They all have a story. I just committed to these two out of a collection and can't wait to get them.
