I have 2 set of the bottle/regulator.
1 is used and 1 is brand new. Both set is similar I will take picture for you. E-mail with your e-mail address. I will send you.
The new set, I paid 150 ( 5lbs co2 tank, filled full, ready to go and dual regulator with soleniod and needle and bubble counter )
marinedepot selling for 149.99 plus 75.00 for a empty bottle, cost you around 12-15 to fill it up.
The old set, I can do 100, same as above but USED. The bottle is not the nice aluminum type.
