I have a KMD 150 in my RV-8 and think it is a great VFR GPS. The display is easy to see in any sunlight. It is simple to use, which is important to me. It drives my autopilot just fine, just remember to program it to do that in the set-up mode.... The only bad thing about the unit is that the price has been upped quite a bit in the past two years. However, I'd still buy another one.
