I have Dynon Skyview and ALL the updates are totally free with no yearly subscription. Garmin, I have heard, charges quite a bit, others are somewhere in between. If you figure in the update costs over a few years it may change your mind about just looking at first cost. With costly updates you also may be more tempted to fly around with out-of-date information or forego the latest new features.
