Any preferences for the CatEye Velo 7 (Velo 9 not in stock at the place I'm looking to make an order) over Enduro, or vice versa? (The appeal of the Enduro is that it's supposed to be extra-rugged. I am a klutz, hence the appeal of that feature. But at this source it's $32.97 vs $27.49, so wondering if it's worth the extra five bucks. I pretty much only want a computer to use as a speedometer for the sake of basic curiosity as to how fast I ride, so it's not worth spending a ton.)
