depends what you want. maxflow is realy good if you rund low pressure. exemely high flow, low shoot down, might eliminate the need for a second reg. its a good system, but it doesn't work well above 500psi output.
so if you dont run lp look elsewere.
and in my oppinion paying $600 for a tank and reg is a little much.
standing here all alone is not as bad as one might think
