Repairable. Take it to a paintball shop if you aren't comfortable fixing it. I just picked of a five pack of battery connectors from radioshack for 2 dollars. Took about three minutes to strip, splice, solder, and heat shrink to a like new finish
Removing the board from the hoses and capacitor (circle thing protected by a metal shield)?
I just meant removing the board from the trigger frame so the solderer wouldn't have to deal with the excess weight of a whole paintball marker. Removing the t-piece from the solenoid would be good as well so the repairman would be able to place the board where they are most comfortable with as few obstacles as possible.
