Wow! How to enable you to spend your money for all the great possibilities!!!!!
First, cheaper, box-store springers work; they just take more effort to work.
Second, a first springer is just that: your first one.
Third, to buy only once, buy right the first time.
Fourth, any tuned pellet rifle is probably going to excel over one that's out of the box.
Fifth, most German made rifles are really wonderful--Diana, Weihrauch, and Walther. Now, the Brits make a great rifle, and there are several other well made ones, too.
Hope you find and enjoy your first spring, along with all the subsequent ones.
