So I'm entertaining the idea of a cycle computer. Ideally I'd like a combined Cadence, HRM, Speed I do not want GPS. Can be wired or wireless. I'd assume wireless is more expensive. There are just to many cycle computers to choose from. Cateye, Sigma, VDO, Topeak, Shimano, Vetta, Serfas, etc.....

I'd like to spend under $100. So what system has the best bang for the buck ??
