Plenty of good entry level springers but most will have the same issues with crappy (or at best so-so) triggers. A good aftermarket trigger for Gamos and many of the Chinese (frequently major company branded) guns can be had for $35 delivered and it won't be hard to install if you have a screwdriver, drift punch (or common nail), and a pair of needle nose pliers. I have a 2004 Gamo Shadow 1000 and like it but it's had a new trigger installed and can still be frustrating to shoot.
Biggest thing with any springer is figuring out how to shoot it and the pellet it likes. They just don't operate like firearms and you can't just grab one and shoot it like your 22 or 30-06 with much success. I'm no airgun expert (exactly the opposite) and am still trying to come to grips with them.
That said, if you get one and learn to shoot it, it will make you a better shot with "real" rifles. And after the break-in and learning and pellet-choosing period, it won't cost you a lot to shoot a bunch, which will also make you a better shot.
You might check around the various airgun forums for advice from people who really know what they're talking about. Good luck. -WSJ
