I looked at a SKB, Spartan, and Stoeger today, (on another note, why don't some gun shops oil/wipe down there guns ahhh!). I'm not drooling over any of them, but I'm still considering. The Stoeger I looked at could be picked up cheap ($200 or so), and the store owner said they've had it a long time, its already got some tarnishing/light rust from handling (and its new), they said that SxS don't do well in their store-I would think not it you let them rust on the rack....
I'm hitting the marsh with the 870 Wingmaster 30" barrel in the morning, the geese are here, and I've got a fresh box of T's-should be fun!
