Ok.. so it sounds like a resonable size tank would keep a good volume of water (assuming my drilled well comes in with a good amount of GPM)

But it seems like 4 hundred bucks would be well spent at harbor freight to boost up from 40 to 60psi.. to up around 60 to 80.

Not quite "hotel water pressure" (I travel a lot and a REAL good shower at a high quality hotel is one of the few things I wish I had at home) but as close as I will get.
