Here are some tried and true paintball resources on the web. Use e-bay at your own risk, but good stuff can be found there too.

Resource Sites:

• Warpig - The oldest, with lots of stuff.
• Action Pursuit Games - Probably the best paintball magazine
• PBReview - A decent paintball review site

Online Stores:

• Actionvillage - Great service from these guys. They have most paints, too.
• I&I Sports - Lots of stuff, but from California.
• Skanline - Long time vendor, great for parts.
• Hotshot Paintball - Newer Mass vendor, slightly smaller product line.
• Boston Paintball Supply - The local guys... the only game in town at one point.

Paintball Fields:

There's a pretty decent listing of New England paintball fields Right Here. Just click your state to see what's around you. Don't forget about Friendly Fire, the Disposable Heroes' original home field...

Don't forget to look on pbreview for updates on fields that people are actually going to.
