For your CO2 bottle, try your local welding shop or fire supression location. CO2 bottles are expensive to ship and cannot be shipped with CO2 in them. As for your all in one regulator/needle valve/bubble counter there are 2 main brands (there are others but these are the mainstay).
Milwaukee
JBJ
Azoo is now gaining a foothold.
Its 6 in one hand 1/2 a dozen in the other.
Depending on who you talk to they are all great and all have problems. I think people are leaning towards azoo and Milwaukee now. I own a JBJ and love it.
PH controlers aren't necessary IMO and IME. An $8.00 timer to turn it on and off with the lights does most of us just fine.
