Need help choosing HRM

I got a $75 giftcard from Target for Christmas...I've decided to use it to buy a HRM. I was looking at their website but I have no idea what to choose. They had quite a few in my price range, but not all of them have reviews. Here are the ones I'm looking at, if any of you have this kind, any info would be greatly appreciated!
