What's a fair price for a Benelli M1 Super 90 with all the accessories to make it both a full Tactical setup and a full Field setup?

18" barrel with ghost ring sight and interchangeable choke tubes and 28" ventilated rib barrel with interchangeable choke tubes.

Pistol grip stock and straight stock.

4-round mag extension and mag cap with hunting plug, plus springs for both.

Sidesaddle, SureFire front end, Giles sling.

Any ideas? Thanks.

I also would like to know where you can get a 24"-28" field barrel.
I have a M1S90 w/ rifle sights and no choke tubes, paid $800 for it used.
