The closest I could find that met your requirements is a Beeman R9 in the package is ~$600
Other available rifles are more expensive, too fast, or don't have a lifetime warranty or accuracy of the Beeman.
Gave a couple dozen rock chucks the old dirt nap with my R9 just yesterday. A high quality springer is an engineering masterpiece and a joy to shoot......a cheap one is an awful experience all around.
Old pic, same result.
