I have been playing paintball recreationally for about the last 3 years. I just started playing regularly (i.e. every week) a few months ago. Jaegers is my "home field". They have a fatasic staff, and the fields are nice. As a number of folks have stated, their paint is a little expensive. I have been playing there often enough, that I just paid $50 for a membership. This gets my fee discounted by $10, so my fee is only $5 a day for 12 months, and I get $5 off paint prices. They will also give you a free field pass for 120 days (4 months) if you buy a gun there. The reffing on the outdoor fields is good. Playing in the caves is fun, but it's kind of on the honor system when you get tagged, as it is hard for the refs to see everything. Their primary concern in the caves is safety.
Every sunday (in the summer at least) they put up the airball field outside. A lot of teams come here to practice, so if you are new to speedball, as I am, you might be outclassed. I like it that way though, because most folks are pretty friendly, and willing to offer pointers between matches. If you play with people that are better or more experienced than you are, then your game will improve.
In summary...their fields are fun, their pro shop is okay, their staff is great, the reffing is fair, and if you do it right all their prices are decent.
