I've gone to EAS 4 times and I've enjoyed it every time. EAS was the first place I ever played paintball and my good experiences there really got me interested in the sport.
Price: Pretty cheap. $10 field fee and $15 for a bag of paint (RPS Stingers I think but sometimes they have other brands). Rentals are $15. Air fills are cheap and free if you get a rental. Rentals are usually Tippmann 98 customs though one time I got a Piranha.
Staff/Service: Great staff. Everyone is helpful and friendly. I needed a mask one time and they gave me one to use that day for free. My marker was leaking once during a game and they gave me a rental to use for free. Another time I needed to run and get more air in between games and the refs waited until I was back before they started the game. I went there twice with a friend and we each got two free play passes for the summer b/c they knew we were noobs and wanted us to keep coming. I don't know if they can fix markers here, there isn't really a proshop but they do sell some items like pods and goggles.
Safety: The refs are very careful to make sure everyone keeps their masks on in playing areas and barrel bags on in the staging area. I've seen kids get yelled at for taking their masks off. There are usually at least two refs watching every game so they can make sure everything is safe and fair.
Fields: EAS is great for woodsball. They have a two story fort for attack and defend, a wooded "village" for CTF and hostage and another wooded area for elimination and CTF games. The fields can be a little muddy and wet in the spring and the first time I went there the brush really needed to be cut, but that had been taken care of last time I went. They have one speedball field and I think there are plans to add another one and one more woodsball field.
In conclusion, EAS is a great place to play woodsball and rec ball (I don't play speedball so I'm not going to judge their speedball field). My only complaint is I wish they were open more hours than just 10 to 3 on the weekends but that's not a big deal.
