I've got one of those Norica guns sold by Beeman. It's an S-1, same as the Norica Jet, or the model 85 as Norica use to call it. 825 with 7.9 gr CPLs, quite accurate too. The trigger is very nice, and better than anything you'll find on any gun in this price range here. I paid $175 for mine. It is a big gun, near 4 feet long, and heavy, and has a good kick to it.
Most guys who call themselves serious airguners dislike Gamos. I think its because in the past Gamo has provided very little in the way of product support, especially in the spare parts department. Of course, a lot (but not all) of Gamo guns are not exactly high quality stuff either. Lots of plastic, cheesy parts, etc.
