Heart Rate Monitor Suggestions, PLEASE and THANK YOU

Options
I bought a Polar FT4 in February. At the end of July, my Heart Rate Sensor completely quit. It had been acting funny for a while, but I contacted customer service and they sent another (free of charge). IT has quit. I was expecting for it to AT LEAST last a year. No dice.

The reason for my post is that I need suggestions regarding a new purchase; preferably NOT a Polar.
