I owned a Marauder but sold it. I didn't like dealing with the SCBA tank or hand pump. For a newbie to airguns, I'd look at a nice simple spring gun or even a Sheridan pump up. You still have a pumping issue with a Sheridan, but it's much lighter and you're not out a lot of money if you get tired of it. The RWS 34 the original poster recommended would be a good starting spring gun for hunting. And yes, the 22 has the edge for killing pests.
