I remember seeing a thread about this a few weeks back but can't find it now on the search function for love nor money.
So what's good in your experience? I've got a cateye 3 LED now and it only needs for it to be a mildly humid day before the switch packs in and it starts playing silly beggars. It's currently sitting on my radiator next to me scrolling through its' various functions all of it's own accord...ACE I need something that is going to function in shite conditions, needs to be small also so it can sit on my road bike seat post and not catch on my legs as I pedal. A belt clip for securing on my Camelbak when night riding is also a must.
Am I asking too much?
