I am not trying to convince you the M2000 is a bad gun and only yourself can make the decision however, you might want to check these two forums then decide whether the M2000 is for you or not:

It is hard to make any suggestion without knowing what's your plan on using your shotgun for.
Is this your primary waterfowl gun mainly shooting from the blind or do you do more upland with a lot of walking or you just need a turkey gun?
Do you hunt big game with it or just use it for birdshot?
I am sure lots of other seasoned shotgunners will chime in once you provide more data.
