The "stuff" that goes along with the PCP habit has kept me off of them. It's hard to beat a classic pump Blue Streak, but to their credit the springers don't sound like a pellet rifle to the neighbors. PCP, C02 and pump do, even when moderated.
A C02 pistol is a whole lot of fun, indoors with a pellet trap or out.
The only watchout I'm aware of for springers is they need a dedicated safe-for-springers scope.
