I've rented in the US and Canada. The area I've kept going back to is Utah/West Colorado, renting from Grand Junction, Colorado. No landing fees, almost new aircraft, well equipped, and costing little more than what I pay for my Group share flying in Scotland. Weather is also good and predictable. Big difference is aircraft performance at altitude and temperature - but a 180hp C172 with 2 up has the same climb rate there as my DR1050 at Max AUW at sea level.
