The only one that has a back-lit screen at that price that Performance sells. Just so happens that it also has temperature and calories. Not a bad computer, have it on my mountain bike.
Also, the edge 500 is fantastic, but quite more expensive and fancier than what you want, that's what I use primarily.
IMHO, I think that basically gives you the 2 options. Either you get something fairly simple and cheap, or you get the Edge 500. The Edge 500 sets the price point low enough, and is desirable enough, there's no reason to buy an expensive computer that doesn't have GPS, and Ant+.
