Ion's have been good starter markers. If your new to paintball, and either don't have a lot of money or maybe don't want to spend a lot of money on a marker, these things will do 15bps straight out of the box for about £120 new, or about £80 used.
It 's easy to say Ego's or Dye's or whatever are better markers, but bloody hell of course they are cos you spend more flipping money on them.
I started on an ion, and now own a PMR and soon to have a PM6 delivered. The ion served it's purpose and allowed me to start in paintball by not spending a lot of money, just to see if it is really something I would enjoy and would want to do.
So as you can see I'm not the 'sort' who has a sponsorship. or the 'sort' to throw money away, quite the opposite in fact. Mate.
Again ion hating isnt justified. Normally ion owners are the ones to hate.
