I am not sure about the JBJ system as I have not used it but I have been using the Milwaukee regulator with solenoid and bubble counter for a few months and I am very happy with it. I do not use a pH controller as there are other things in the water that can affect the pH. I just watch my drop checker and turn it on via the solenoid an hour before lights on and off an 30minutes before lights off.
Check in your area for CO2 places, AirGas or others, and you will probably find the tanks you want available there. Also I got a refurbed 10lb tank on ebay for $70 shipped!!
You will defenitely need check valves, brass one probably the best, but I got mine at work so I am not sure where the best place to get one is. If you go with the Milwaukee system at Aquabuys then you will need CO2 tubing also.
