What's your fill source going to be? You can get away with hand pumping. I did it for a while until I got more PCPs and larger calibers.
If you're using a compressor, who cares how much you have to refill the tank? That's why I mostly shoot 30 calibers now.
Mauraders are nice rifles but I would rather save money and look at Air Venturi Avenger, Umarex Origin... especially if you are thinking of hand pumping, those guns don't have huge bottles. Supposedly the Origin is very hand pump friendly. I haven't ever touched that gun but I've seen enough reviews that if I was getting into PCPs all over again, that would be at the top of my list. Along with the Avenger which is more tunable and has a proper regulator.
Maybe if you have $700 to spare take a look at the new Air Venturi AvengeX lineup. One of those would have almost twice the power of a Maurader in 25 caliber (or 22 caliber), supposed to be very efficient per shot, and you can get wood stock, synthetic, bullpup, tactical etc configurations. They should be available very soon.
