Windshield mount for Echo in full tablet mode.

[huydat]

I just got the Echo for my parents (their first Andriod phone). I've been searching, but I can't seem to find a good (inexpensive) windshield mount solution for the Echo in full tablet mode. The primary use would be for navigation in the car. Arkon's got an option (intended for 7" tablets) but it's a little pricey (Tablet Car Mount | Windshield Mount for 7" Tablets). Anyone seen something similar?
Also, the leather-esque case that they sell at Sprint for this is "ok"...but $25 is a bit much.
