i prefer the ion for the simple reason the amount of ppl its got involved with paintball yeah it might not be top of the range but with a few mods its keeps up with top end markers + most faults with ion are simple to fix, only problems i know of are eye cable getting trapped in grip frame = get new cable, solonoid/board/batt cable (most ppl changeit anyway), leaking hoses = put new hoses on) this isn't rocket science the rest is simple maintainence.
