Sherwood Forest - Great if you like woods ball, slightly more expensive.
Blast Factory - Excellent indoor place. Prices about average. Good turn-out.
Super-friendly and accomodating staff, relaxed atmosphere, competitive prices, well-stocked pro-shop, fantastic indoor airball field and another smaller speedball field made of plywood. There's usually a good turn-out, and good competition. The outdoor hyperball fields are top notch if it's warm enough to play on them. One great thing about the Paintball Heat owners is they're always improving it. I highly recommend it if you can make the trip!
