I'm trying to decide on a G.P.S. I'm leaning towards the Cateye Stealth 50 because it seems like a decent unit with some features that I really want (H.R.M.) Ant+ and not a bunch I may never use. Plus I really like the backlight feature for night rides. The price seems reasonable. Any thing I'm missing or other units I should look @ in the same price range? Also I would REALLY appreciate suggestions on where to purchase. I seen it for sale the other day for $100.00 but that deal expired. Suggestions??? Thanks in advance.
