I would also recommend the PGP.
When looking at them though, make sure that you're getting one with a velocity adjuster. Earlier ones didn't come with them.
The extended cartridge knob is also a big plus (they unthread much faster and keep you from holding the pump wrong shooting your own thumb) as is getting a cartridge-valved gun.
If you can find one, the PGP2 (distinguishable because the center tube (barrel) extends about an inch forward of the other two tubes) comes with all the essential upgrades. You should be able to find one in good-great shape for $80 or less.
