Most people in fitness believe that POLAR is the best all around HRM brand. Which POLAR monitor is a more difficult question.

What do you think of these heart rate monitors?

Of the 5 heart rate monitors on your list, I would narrow it down to Polar FS1 and Sigma PC 15. Polar FS1 is VERY basic, but that may be is what you want. Sigma PC 15 is quite advanced, but really cheap for what it offers. Both are good quality products, one Finnish and the other German.
