we used Castle Carts this time (for the first time) and they were terrific. got a great rate (better than moncho's), the cart worked (a bonus), and we got the cart picked up and delivered to the airport. AND it had a windshield so the dust wasn't so bad.
I agree with KLC. Veronica and Inmer are great to deal with. They delivered a new clean dependable cart to us north of the bridge (some companies won't deliver north). Also gave us a great deal... Will be renting form them again in January.
