Color displays eat up batteries. I you power it off the airplane, thats
not an issue. I have a Garmin 195 which is Black and White and it has
served me well. If you fly a lot, batteries are a hassle. I would try
and get a solution that doesnt mean batteries, if possible. If that is
not possible, I'd get a Black and White unit. They do the job, and you
are waaaay better off with a B&W working unit than a color that has run
out of power and is now shut down.

How long does it run on a set of batteries? With Rechargeable NiMH
batteries affordable this may not be that big of an issue.
