I would use two regs: one after the tank (palmers perhaps) to go down to a safe head pressure for an LPR, then for the LPR, any adjustable regulator will work, even one you would use for shop air (under 200PSI). you just need to decide how much flow it needs (rate of air consumption and cycle for your application) as well as how small/compact it needs to be (bigger regs are cheaper). an adjustable LPR from say, an autococker, is both compact, can handle higher head pressures, and may cost you pennies buying one used online... so it's basically ideal (the only limitation will of course be the flow, they don't really compete with a larger LPR).

Also with the cocker LPR, you wouldn't even really need the first regulator, they can handle 800PSI just fine.
