Off-topic / GPS question

A friend gave me a Garmin emap GPS from 1991. It's old but it works.

Anyway, I would like to upgrade to a more modern one, I can actually still sell this for about $80.00 to help offset the cost.
I would rather have a hand-held unit, and I won't try to program it while driving.

This would mainly be used in the car but may be taken hiking as well.

Can someone recommend a best bang for the buck on a GPS? I never thought I would use one but I am finding even the older unit helpful.

Thanks!

Pat
