I ended up installing it at my house.... well... I did all the plumbing, haven't had the time to actually put the pump in place yet. I'm on a public well (about 14 houses share a well) and the pressure varies from about 25psi to 50psi. Though it's more often the 25psi than the 50. Mostly bothers me when taking a shower or taking a pull of water from the fridge. When it's low pressure not much comes out, about like having the dog piss on my back or piss in my water cup.
They sell them at Lowe's now, it's not terribly expensive. It's a shallow well pump with the pressure switch. Probably good idea to put a bladder in as well.
