I was responding specifically to the guy suggesting the eNMEy as rentals. Our local field tried out the Gryphon as a rental as well, and they're just not dirt-simple and overengineered enough to put up with extensive neglect, even with only playing indoors.
As far as growing the sport? The best and biggest thing we can all do as players is turn the testosterone down about 700%, and play to have fun rather than treating paintball with the same toxic bulcrap attitude that comes with the competitive first-person shooter video game.
Sportsmanship is a necessary minimum. 'Whatever you can get away with' seems to be more and more the standard of behavior in a lot of places, and that creates a serious barrier to entry for new players.
