Can't really help you out with woodsball sites but there is a woodsball section on the main forum page. If you want to share where you live I'm sure people will be able to help as most of us on here play sup air ball.

Seriously, don't skimp. When I first started out I bought the cheap and nasty stuff to get my started, wasted a good £500 (on a several other guns and hoppers) until i realised that buying something good straight off the bat would have saved me the hassle, time and money.
I hear ETEK's are the way forward, or any good planet eclipse gun bought second hand from this website if you look in the for sale section. The sellers on here have a good rep, but you can always double check on their seller feeckback thread.
If you have any further questions post them up, people are bound to be helpful!
