That Beretta hammer gun Steve Barnett sold was mine a couple years ago. I wonder what he sold it for.... I think I paid $700 for it! Great gun... very much like the Bernardelli hammer guns.
Here are some other gun I've owned that might serve you well....
Gasperini Hammer Gun
The hammer gun I'm holding here is a Thomas Wild back-action hammer gun with 30" bbls and a rounded pistol grip. I sold it to a good friend and have been trying to buy it back ever since.
Here is a Bernardelli 20ga... though, with your budget, you could get one of their higher grade guns.
Here is the Beretta that has already been posted (the one sold by Steve Barnett). I sold this gun a few years back.
For hammerless, you may want to search for an AYA #53 or #56. They have pistol grips much often that the #2s.
