I like how on these type of treads one of the first questions back to the OP is what is your air source. That’s actually a biggie and should be answered by any OP wanting to get into this sport. Knowing what the air source is will help with the suggestions back.
From what I’m taking from the OP’s description of what he’s looking for, I, too, say a Marauder. Very easy to maintain, parts are readily available stateside, o rings can be had for the local ACE hardware, and leaves room for a hand pump and/or a scope.
