As always, what ya gunna do with it? Shoot paper or hunt, both? something else?
For a first PCP (there will be more!), I'd still go with the Marauder. Plus I'd go for the .22 version. Why?
New barrels from Crosman are very good. Reviews are great. I have an earlier Gen 2, and at 50 yards, very accurate. Got good trigger (most less expensive guns triggers are really bad).
Big thing is that if you want to tinker, it has adjustability no other entry level gun has. You can tune the gun, not just look for the best pellet that might work. Hammer spring, tension and the transfer port are all adjustable. No other entry level gun can do that.
If you want to have a regulated gun, you can buy a Field and Target, or add a regulator later. If you after market parts, the Marauder has a huge after mareket.
For paper punching, the .22 is good to 75 yards or so is my experience. Tune it down and you'll get 50 shots per fill, very accurate, and about 21 foot pounds,.
For hunting, the .22 is plenty of power, setting up to 30 foot pounds and get around 30 shots per fill. All depends on what you want.
Everything I learned on the Marauder was directly transferrable to the Impact. It's a great learning platform.
Good Luck
