@Jason30, the reply from @intenseaty22 was on target - know what, for you, defines acceptable performance at an acceptable price. For instance, my Benjamin Summit NP2 break-barrel in .22 will shoot 2-liter bottle caps at 50 yards all day as long as long as I have a decent scope on it and use pellets I've found to be accurate for the gun. It took me a couple of months of testing different pellets, learning how to hold the gun for best accuracy (artillery hold, naturally), polishing the sears in the trigger group for best performance, laying hands on a real quality scope... all things I learned to do by reading material here on AGN and then going to YouTube for follow-up on specific topics.
I have another gun, .177 from Walmart (!), that gives me sub-1" groups at 25 meters in my own yard. Can a PCP do better? Oh yeah, by far. OTOH, that Walmart break-barrel cost me under $100, including the washer bearing and replacement trigger adjustment screw (see "Crosman trigger fix" on YouTube), plus another $55 for a scope. Compare that to the $400+ that you most often see cited as the cost for a beginner's PCP by well-meaning airgunners who share opinions here on AGN. And that only gets you into the low end of PCP shooting. Even a used European springer will easily cost double my Walmart gun, to say nothing of still having to put decent optics on it.
What I'm saying is that only you can decide what price and performance will satisfy you. There is a HUGE range of "traditional" air guns out there and, contrary to oft-repeated opinions here on AGN, many in the $100-$250 range can be excellent shooters with only a little TLC and a minimum of mechanical inclination. I am living proof of that - seriously. If you want to go for a high-end springer, new or used, more power to you. I tear up while watching some of the British guys use their Weihrauch and Walther spring rifles, thinking to myself how nice it would be to have such lovely guns. Then I go out and shoot my Crosman, Gamo, and Benjamin spring rifles at 25, 50, and 100 yards and find that my accuracy is getting better, my groups are getting smaller, and the guys at the gun club are getting more and more interested in "modern airgunning" as they see me picking off bottle caps at 50 yards and shattering clays at 100 yards. Decide for yourself what meets your need - the airgunning world is your oyster, man!
