Ok, i have been using the Simplex for the last two yrs and been thinking about getting another detector since my wife has taking a interest. The two i have been looking at is the Legend and the Equinox 900. The question i have is between these two is the simplicity. Is one easier to learn or more complicated then the other? Build quality? I know there is a big $ difference between the two but not a issue. Thanks for any advise.
