Fitbit Charge HR Heart Rate + Activity Wristband Starting $109 @ Walmart Ships Free or In-store
Large Black is $109 and I price matched to Best Buy as I had some reward certificates.
There have been several ebay sellers and posts recently for $85, including this recent Front Page, but this is the lowest price I have seen from a major retailer. Lowest per CamelCamelCamel on Amazon was $109 in September of 2015.

3.5 - 4 stars is about max rating on ANY of these sports bands. This is the #1 seller on Amazon, but is $126
Also, I considered others in the price bracket of sub $200 with heart rate, but came back to the Charge HR because I really just wanted something to track my activities a bit better than my iPhone. BTW, the app is very solid. I based a lot of my decision on the Fitbit Charge HR on these videos:

Close second choice, but did not like the height of the band and always have my phone on me, and let's be honest, I am no way athletic and would benefit from the features, but this is an awesome band.

Finally, I also recommend just downloading Fitbit app on whatever phone you have before purchasing this as you can use without a Fitbit.
