If you are looking for Aero/Glass style icons… check out http://www.vistaico.com/

This is a spin-off site from http://www.vistaicons.com/ where you can find a few more icons… I’m still trying to find the money side of this (I’m assuming you give away good icons to lead to a purchase of more? But I can’t find any to buy…) so let me know if you figure it out.
