Anyone shooting PCP air rifles? Looking to get started with one.

I am thinking about picking up a mid range PCP like a Benjamin Marauder or Kratos, thinking .22 cal for the first one. The big hurdle for me is the air tank. The better air tanks can cost more than the rifle. Anyone shooting PCPs and have any tips on tanks and recharging the rifle without spending an arm and leg? Any places that can fill a 4500 psi tank? With the ongoing ammo shortage I don’t want to dip into my stockpile but pellets seem very available and not very expensive. I’ve got a few acres so I’ve got room to shoot, plus plenty of various varmints to whack.
