Get a 70ci with a red (hp) reg.
I plan on getting a new marker later on (next year) , possibly a PMR (sorry for bringing that into the cocker forum) but it only runs on LP because it has no LPR
. I've heard that a LP tank is ok on a mech marker because it only get's like 9 bps +/- 2 without getting shootdown (which I still don't fully understand what it is btw).
