Good places for rams, valves etc- airlines pneumatics- they sponsored us with several parts for shockwave (http://www.airlines-pneumatics.com/http://www.airlines-pneumatics.com/)

Regulator- Email Trevor Wright (Mighty Mouse, Velocirippa etc.) He makes the ones that we use

CO2 bottle- email Jonno- we got ours from him.

The regulators that Trevor makes attach directly to the bottle and it does freeze occasionally- I run them in both Shockwave & Tidal Wave 2 with no problems at all.

The thread on the bottle is the same as a standard fire extingusher so no filling station is needed.
