Like Todd, I rent mine as well. This way it gets back to me for others to use.
I live, e-mail me direct and let me know where you are, maybe our paths can cross and save you the rental fee. (I only charge $10.00 and you get back $5.00 when you return it).
I just looked at your profile and see where you live. I travel to Cleveland airport 5 days a week as well as Akron Canton 2 or 3 times a month. Let me know....
