I am interested in getting a Kral Puncher S but have a few questions about refilling. I would like to know what you guys recommend, a SCUBA or a hand pump? I weigh 66kg so I am not sure if I will be able to pump the puncher all the way to 200BAR. The only problem I have with SCUBA tanks at the moment is that it seems as if they are really expensive since the cheapest 10L 300BAR dive cylinder costs R5 100 and the gun itself costs me roughly R7 000. I also can not seem to find a place to buy a cylinder in Kempton Park.
