I don't know, that is more than half of what they are new, and you don't get screw in chokes or anything. Not to mention if you were not stuck on it being a "wingmaster" you could get a brand new pump gun for less than what that one is used. Not to mention it would shoot 3 inch shells and come with screw in chokes. It just wouldn't be as pretty. Heck I think if you looked around you could get a combo with a rifled barrel for that kind of money.
You could get a nova and it would chamber 3 1/2 inch loads if you wanted, they are butt ugly, but they work
Or you could get a brand new browning BPS for around 450 or so and they are just as pretty and work just as good as a wingmaster in my opinion. Plus it will chamber 3 inch shells and comes with three choke tubes.
Options, Options? Really depends on what you want I guess. I just paid almost 500 bucks for a used A5 when I could have gotten a new auto for that or less from another maker. I decided that is what I wanted though.
