It was 10 years ago so may have changed but I rented a 172 from Flight Training at Lunken (Cincinnati Municipal Airport). Excellent airport and friendly people at Flight Training, reasonably cheap and fair condition aircraft.
Make sure you get all the necessary licence clearances and approvals from your CAA equivalent BEFORE you go (not sure of all the details but it was all tightened up after 911)
