I've used mine for 2 years in my car and motorcycle and now has completely broken down. I called Garmin and they gave me a good price on replacing it for a refurbished model, however, they told me that I should be aware that I would not be able to install up to date maps because the 2720 does not have the memory space to take the new updates.
I bought a new waterproof Nuvi 550 from GPS City for around $215 and so far it works great.

 

Very good info from all of ya, thanks!
