PCPs are pretty cool. You have to be pretty serious about air rifles. The Marauders are never a poor choice.
Knowing that I would eventually grow bored of mine, I got a Stoeger X20S and upgraded the trigger. Its pretty darn accurate, as well as quiet. The barrel has a true integrated suppressor baffle system. Its not as quiet as my suppressed 22 LR using subsonic ammo, but quiet enough for me at half the price of the Marauder.
Like I said, however, a Marauder is never a bad decision.
