CO2 FTW.
A ‘Powertank’ can be ‘made’ for ~250, depending on the quality of parts you choose.
The most expensive is going to be the regulator, 150 shipped from wheelers.
I would NEVER go with an actual PT; for a couple reasons. 1) most places just exchange tanks, not refill. (Read: bye bye pretty powder coated tank.) 2) it’s way to damn expensive for what it is.
Here’s my build to my ‘DIY PT’; along with a video of me airing up my 37s from dead flat, to 35PSI.
