HRM and sensor suggestions?

Terree_G

Is it OK to use just a watch HRM or do I also need to buy the sensor strap to wear on my chest?

Also, what is the best buy for the quality and ease of use? I am looking in the $150 range total for both items, or up to $100 for just the watch.

I'm sorry if this topic has been covered previously (I'm sure it has, at some point) but I did look first to see if there were any posts on the topic.
