I thought it was cheaper to build one by myself till I found one by aquatech of California for 64 bucks. Its not dual stage but if your worried about that you can always add another tap before the needle valve. It came with a solenoid 2 gauges and a needle valve. No bubble counter though. I got a glass one with a check valve for 6.20 shipped.
You don't have to get a pH controller but if you don't you should get a drop checker. This measures the amount of co2 in your water with a color chart. Green leaf's look really nice (just got mine 2 days ago)
I don't have a pH checker but I will probably invest in one when I get a bigger tank since my tank is just 29 gallons.
About the co2 just leave the door open to the room or you can get a co2 leak checker and every so often check for leaks
