FWIW, if you ever break a Garmin you can send it to them for an exchange/repair that isn't too expensive. I crashed on my 510 and they replaced it with a refurbished unti for $75 which was a lot less than even a used 510 on ebay.My 810 broke off my out-front mount and rolled down a hill, effectively trashing it (I still got $100 for it, if that's any consolation).
Garmin Edge 810 or 520
