I was originally thinking I would get Protons, but the more I researched the more I started thinking Zonda. Came across a deal for Zondas in the mid $300's and pulled the trigger last fall. ('06 version) I love them. Roll great, smooth hubs, perfectly true after 1200 miles (I'm 235ish). Crosswinds are noticable, but not bad.
Had a racer friend get the new '07 versions ... he had problems with loosening spokes and returned them. I love mine.
