From the responses, I'm guessing there aren't a whole lot of fans of the RBL's, for that price range?
A mint RBL 20 at $3K is a good value. At $5K, not so much. I have RBLs in 20/28" and 28/30". Good guns for the money.
Re Stan's suggestion about Italian doubles, there are some good values out there in V. Bernardellis, Berettas, and FAIRs, but they can be tough to find. And maybe Faustis. Rizzinis can get pricey. I have a 20ga Beretta 426E, and it is the only one I have ever seen, but it is very well made, maybe a bit heavy.
