Cessnaflyer,
You're planning on a Instrument check ride shooting non-gps approaches requiring DME using a GPS with an expired database for DME?
My guess, and it's only a guess, is your check ride will end early. The money saved on updating the database may be less than the second check ride.
If you can fly a VOR approach, you can fly a GPS approach and the GPS approach will be easier. I'm not sure what you're afraid of?
I took my Instrument check ride in 1978, long before GPS and iPads. Few flight school aircraft had a working DME. Situational awareness was so hard to maintain, the first time you knew you were close to a VOR was when the flag changed to from. I bought my current plane in 2004, it had a GNS430 when I purchased it. It is so fricking easy flying with GPS, seeing the fixes, being told by the GPS when to start a turn, knowing where you are at all times with simply a glance, I still shake my head in amazement.
