I agree with Geo Climber also... I briefly contemplated the Legend or the Vista and finally decided, heck, what's $30 in the greater scheme of things...
Once it arrived, I found the compass interesting. Even handy to have in certain circumstances...
However, the altimeter, it turns out, is very interesting to me. When cycling or walking up hills, you know the total elevation gain. I next wondered, how accurate is it? Well, I wouldn't bet money on it, but I have done the same hills around here on different days and found that it arrives at nearly identical elevation numbers. What is even better is after going for a bike ride or hike, you can clearly see the hills you climbed via reviewing the elevation history graph (which can tailored to your liking).
So, bottom line is the compass / altimeter feature worth $30...? Absolutely!
