I bought a Maverick model 89 Field from Walmart for under $200. It's a 12ga pump with black synthetic. This gun is basically a less expensive version of the Mossy 500. (Maverick is a sub-company of Mossberg). I've shot dove loads all day though it and it was a joy. No problems whatsoever.
The only thing I've encountered is the front bead is very whimpy. My younger cousin knocked my shotgun over while it was leaned up against the truck and the Bead cracked and fell off. but then again, it did hit gravel.

just my $.02
