Beretta also made hammer doubles under the MiVal name (or something close to that). V. Bernardellis are great guns for the money, but the POW grip may be hard to find on a hammer gun. You could get a pretty nice Parker or Birmingham hammer double for your budget, but likely to be Damascus or twist barrels. Your best bet for a modern hammer double (other than Bernardelli) is probably going to be a used Spanish gun from one of the lesser known makers. I picked up a Sarasqueta hammer 20 last year for pretty reasonable money, with 32" barrels and 3" chambers.
