I need a heart rate monitor and I really don't know anything about them. Does anyone have some good suggestions on what would be a good one to get? Here's my problem: I've started getting pre-migraine blurry vision after my ride to work. I think I might be pushing too hard and I need to start tracking my heart rate so I know what's going on. Thanks! Travis
