Another vote for the Maverick 88. I have a friend that last year picked an 8+1 Mav 88 for $300 at the Valpo show. Stay away from shotguns with ONLY a pistol grip unless you KNOW what you are doing. Another option that is more exotic but a little more expensive would be a Kel-tec KSG, as it is a bullpup with a pistol grip, 18" barrel in a 26" overall length, and two tubular magazines holding 7 2-3/4" shells each.
