If I may throw my two cents in...
When I purchased my Benjamin Titan NT springer a couple of years ago I didn't know squat about airguns. Today, what I don't know could fill a good-sized library, but one thing I've learned is that this is very much a budget-busting sport. I typically research the crap out of anything like this I buy because I simply can't afford to spend money on gear I won't want to use later. For some reason, I read some stuff about the Hatsan Flash QE that seemed like a huge step up from my springer, without busting the bank. Naturally, the support system costs have crept in hard. A hundred here for a hand pump, another buck and change for a used SCBA tank, etc. And I haven't even started to mod this thing.
What I learned the hard way was how this thing works. I had all sorts of grief with the mags not feeding properly only to learn way into it, when I was pretty upset about the whole thing, that a critical o-ring in the breech was missing. Probably knocked it out myself with the brutish behavior I was using to try to seat pellets. But when I had a pellet in there and my scope was set, man did it shoot great. With the o-ring in place, feed issues are zero. Accuracy is excellent. Good enough that I'm going to hold on to this and try to see what I can do on a budget to make it even better. I took 200+ iguanas with the Benjamin, and I've got close to 75 with the Hatsan. Just started shooting the JSB Hades, and wow, does it blow up some iguana.
When all is said and done, if I had the bucks, I would definitely want one of those beauties we see here that cost well into the thousand-dollar-plus range. I can't reach that, but God bless them that can. Whatever you have, just shoot and be happy!
