I own both a Benelli SuperNova Tactical and a Mossberg 590. Below are the positives/negatives regarding each:
Benelli SNT: PRO's: Exceptional quality/durability (probably the best Ive personally seen given the price), great features; CON's: Limited aftermarket parts availability, parts are more expensive than other makes/models, initial mag capacity is lacking thus requiring a mag tube extension for greater versatility.
Mossberg 590: PRO's: Good quality, good aftermarket parts availability, great features, tough; CON's: Sometimes may require mag tube spring change, fit/finish not quite as nice when compared to the likes of Benelli, parts/aftermarket availability not quite up to those offered for the Remington 870.
All other makes, Im just not sure of. The Remington 870 has a strong following, but IMHO, the usual 870 Express models just dont match up to the previously mentioned Benelli and Mossberg models, when considering more than the 870's aftermarket parts availability.
Now, keep in mind, the Benelli SNT or Mossberg 590 may put you above the $400 mark new. So, I guess the alternatives would be the Benelli Nova or the Mossberg 500 (advantage=better parts availability vs. the 590). Both are good guns, but not quite the same vs. the SNT or the 590. But, if all else fails, I guess try out the 870 Express and see what you think.
Personally, as I mentioned before, I think the Benelli trumps them all in terms of overall quality. But, the cost of replacement parts (particularly barrels) and the lack of aftermarket support might be unacceptable to you. Also, in terms of the Benelli, keep in mind that the Nova's stock is fixed, whereas the SuperNova Tactical stock is interchangeable.
If you can, I would sport just a bit more cash and go with either the Mossberg 590 Special Purpose ($450 give or take) or the Benelli SuperNova Tactical ($480). These models are a bit more "robust" vs. the others. The Benelli is "cool" and modern; the Mossberg is "mean" and all business.
Happy hunting!!
