in regards to the amount of o-rings on the drive train all I have to say is thats the price for shooting the best spool valve on the market. I HATE trouble shooting my old school Matrix but deal with it because it is an amazing shooting gun. The plus side is that the o-rings have such a long life before needing changing thats its almost a mute point.
