I think this is worth mentioning. Twin Oaks Airpark, where I'm training, has very reasonable rentals on their aircraft fleet. All the aircraft are GPS-equipped, and the rates are "wet" (which means they include 100LL fuel), which is quite a bit less than most other FBOs in the area. Good for keeping training costs down a bit.
They have seven Cessnas for rent. The four C-150's rent for $75/hour and the three C-172's (all IFR-equipped) go for $99/hour).
For the Piper fleet, they have a cool restored 1948 Cub (VFR), a Cherokee 180 (VFR), and a Comanche 250 (IFR).
You can see the rental schedule for each plane and then reserve the aircraft you want to fly online.
