For some reason the prices on these seem to have fallen over the past few years. It was discontinued in 1991 and had a list price of $1695. The Blue Book shows $1050 in 100% condition and $600 in 98%.
Here's a NIB 20 ga. that was listed for $799, but the listing was closed.
Other than that, I don't know much about that model. I would buy it, unless it was my last $600.
