Just bought one of those Neo Grab holders for $19.99 free shipping on eBay.

Looks great for our cars in multiple locations and the mounting piece sticks to damn near anything it looks like, AND it's not permanent. I'll be using this for Torque, nav, and video recording mountain runs and track days.
