The biggest problem is folks who buy an SPS or Express and get mad because it is not as nicely finished as a BDL or Wingmaster from years ago. They get on the net and complain about quality being down.
The SPS and Express guns are just as reliable and functional in my experience, but you are saving money by getting a lower level of finish and cheaper stock. If you want the better finised gun, they are still availble, but you are going to have to pay for it.
I think they are as good as they have ever been. In all fairness, I prefer other brands, and Remingtons do have some issues, but I do own a few. And would buy another if I wanted one as well as recommend them to someone considering one.
