Airgunner,
Go with the Beeman. My daughter has the Gamo 880, which was the top of the Gamo line with the Hunter 220 near the bottom, and it isn't near the rifle that you get from Beeman. If money is the problem then and you don't mind a .177 then get a Winchester 1000C. From Natchez they are under $80.00 and are better than that 880 my daughter has/had. I bought my daughter one to replace the 880 because of the troubles it's starting to experience. Go to
