I would to, id take it to a local paintball or scuba shop where after its tested you can get a fill, and id get the fill right then and there that way if it leaks they know they are responsible for it and will have to fix it, because if you bring it home then a few days later you go to play and you get it filled up, theyre gonna assume its your fault.
my 25$ hydro ended up costing $90
