What to do with old GPS?

[bonova]

Hey all. I have a number of GPS's for various uses. One of my Etrex Vista's (the Colour one without the sd card) is giving shite. It turns off with any vibration or knock..... even if I run with it.
Is there someone who refurbishes them, or uses the internal parts, or trades them in? Just interested....
