Whats everyone's favorite backup gps (if you fly with one).

It occurred to me that my Naviter and LK are fairly unstable and it would be wise to carry a backup...

Garmin 96 or garmin 195 are cheap, not sure about their power consumption.

A smartphone seems like a much cheaper option if you already have one.

I keep an Android phone in my pocket running XCSoar which gives me all the functionality of a full blown moving map and glide computer with zero additional cost.
My Samsung Note 2 runs for 8.5 hours on a full charge with XCSoar running and maximum screen brightness (GPS on and GSM off). I've never had it crash or reboot on me.
Replace Andoid/XCSoar with iOS/iGlide (or whatever you prefer).

If the satellites are switched off a map is the third option and there is nothing wrong with doing a precautionary landing in a farmers field should one get lost.

The Android app called Avare is excellent, and runs current WAC or Sectional charts plus airport info (eaasily pull up runway width! try that with a paper chart)
It's free, but I feel well worth a donation.
