I am riding much more this year than ever before, and my cheap Cateye wireless is starting to show it's limitations. It is a very entry level unit that tells me speed, time riding etc. I am looking to upgrade to a computer that displays more than that now. I was wondering what you guys would recommend for heart rate and possibly cadence? I am not looking to spend $500 on a setup...but would like to get a solid reliable and accurate unit. A riding buddy of mine has a setup that does a lot of functions, but doesn't do any of them well. I would like to avoid this type of money pit obviously! Any suggestions?
