I'd like to get some info on refilling PCP's. Does anybody use a hand pump or is the divetank method the best way. I like pumping as much as the next guy, but how much physical effort is involved. Does the initial setup cost less with and handpump, and how many charges do you get out of a divetank, and how much does it cost to have the divetank refilled. I know these questions are generalisations, but I just need ballpark figures.
