Hi, Patrick,
If long range shooting is what you're interested in, I'd say go pcp-the Discovery is a decent gun out of the box(usually) and you can add a scope later as your budget permits.
It is a little loud without a moderator (TKO Brake) but as long as you're not trying to shoot in the backyard you'll be fine without one. Remember you'll need a hand pump or scuba tank to fill the Discovery, so now you're into the $350-400 price point. If that's too much for your budget, you can get a top of the line breakbarrel (HW 95) on special from Airguns of Arizona for $299 shipped. That gun is much better quality than the Benjamin nitro piston guns, and it is one of the most respected and accurate guns out there. Keep us posted- always good to see young folks getting into the sport!
