Don't know how much you plan to spend, but there are some good used guns out there that can be had for less. I have a Marlin Model 512 Slugmaster that I've killed quite a few deer with. It's a 12 ga and it shoots really well with sabot slugs below 1700 fps. Tried some faster ones, but they did not group at all. A similar gun is the Mossberg Model 695.
