I've been really happy with $160 Mossberg Maverick 88. I don't think you can go wrong with either Mossberg or Remington.
My dad and grandfather have Mossbergs.
Rem 870 and Moss 500 are great choices since there's plenty of aftermarket parts available to configure them any way you want. Either of those with 00 Buckshot will suffice.
I guess I will be the lone voice of dissention, and reccomend a carbine. One that uses an "intermediate rifle round"(ie 5.56x4/.223Rem, ,7.62x39, .30Carbine, etc)
Who sells good stuff for the Mossberg, Ray?
