None of the handhelds are as good as having a panel mount.

But if you are going to have a handheld, the most satisfactory
solution is to mount a Garmin III above the glareshield (or beanbag
it).

I have a 195 as a backup to my panel mount and I just put it on my
knee, (when I use it at all, which is occasionally as it has better
maps of Class B airspace and has ground feature information (roads
rivers etc).
