Polar Ft1. Simply a chest strap and a wristwatch monitor. Easy to see on the handlebars. So, yes they do exist and the price is reasonable, The watch can do some other things. I don't care. As a monitor it was easy to set up and use. (I had to buy it on Amazon as non of the sports stores I spent a day going to in Portland had it. Tried to spend my money locally.)
Edit: Each of the strap and watch take common electronics batteries and are easy to replace. The batteries I put in last June are going fine. The chest unit is waterproof so taking it into the shower after a ride is no big deal.
