Re: Anyone interested in...
It's easy to spend a grand in it but you would be nuts if you did. All you would need is a mediocre gun, hopper, paint, tank, and mask. When you buy the stuff used you can get very good deals.
Besides just borrow someones gear for your first time out so you can make sure it is something that you want to get into. Most anyone into paintball will have spare gear. I know I do.
