+1 on the Delphi. A 4.0 replaced my old Vetta with a failed cadence sensor. The thing feels well built. Thick, solid case for the computer and a nice thick wire for the cadence unit. The buttons feel excellent. Lifetime warranty. The Vetta that I had before was much cheaper feeling, almost frail.

It also has 4 lines of data: speed, ride time, cadence, and another line that you can choose with a button (I keep it on distance), so you don't have to keep pressing buttons all the time to check different data.
