aero helmet - WTB

I am looking for a small aero helmet to use in Kona. I'd be happy to buy one but if there is anyone in the Florida area (or anywhere) who would like to rent it out to me for Kona that would be even better! I am finished racing this year except for Ironman and 70.3 world champs so the aero helmet would be a one-time thing for this year. Thanks!
