Depends on what you like! Heck your name is sniper you might try a Sniper (a pump version of the cocker) they are great markers! Palmers puts out some real tight pump markers too. With either of those two markers I would choose over the hammer but it is something you should try out before buying!
Try and get hold of a sterling pump a lot of sites use them for customers and they will withstand an awful lot of abuse.
And they rather cool as well.

Why not is more like it. Different strokes for differant folks some like pumps some like semi auto's and it can be fun to play against Angels with a Pump (Ask Alien he does it regular at the OTE walk ons ) and you should see the faces on some guys when he pulls it out ( his pump you dirty minded..... ) mind you we also play with 10 shot pistols to so we are both nuts
Most anything palmer they get expensive but are well worth it, i use a splatmaster as a side arm it does me fine but that is for aside arm for a normal gun a super stocker and i'm not sure about the hammers but my brother has one
