if you dont have time to tinker with stuff, dont get the ion. to do basic maintenance you have to tear apart the whole gun and unplug everything. if you do not do this to clean it (the manual recommends every 2000 shots) you will have alot of problems.
and an autococker will work fine as long as you dont mess with it. if it isnt broke, DONT TOUCH IT, and it will be good for many, many days of paintball
the only maintenance it really needs is pulling out the bolt pin, sliding the bolt out and lubing it up, then put it back in. every 8000 shots or so you should drop 2-3 drops of oil in your asa to keep the internals in good shape. thats about it.
