I've had a Garmin GPS 92 since 1998.
Although the moving map is small (and you check this out by having a look yourself), I find that the long battery life and small size more than make up for this.
I've found the unit to be reliable and accurate - most of the time I use the pages that gives me track, realtive bearing, cross track error etc.
Having said that, as the previous poster says, the Pilot 3 is a very good unit, although larger and heavier than the '92.
