I have the Cateye Strada Cadence which ran me around $50.00, but it's wired. I have a compact frame road bike that the computer is on and the cable is barely long enough to make it from the chain stay to the stem where it's mounted. I have just enough cable to be able to turn the handlebars to just past 90 degrees. I mainly purchased it so I can get speed and distance while on my trainer as both sensors (speed and cadence) are mounted on the chain stay. So far, it has been a very good computer although you have to be careful when changing modes or you can clear your current ride stats if you hold it down too long.
