I just got a pair of hp100 XS Scuba (so Worthington) 3442 psi born 2014 for $350 for the set. That was with fresh hydro and vip. They even have the fancy vindicator valves on them with converter inserts.
I'm sure there's better deals out there, but that's what I was willing to pay.
seems you norther divers or people on the coast see better deals. He could probably find a better deal where his is located. Deals are kinda sparse in the land locked locations.
