The first one is twice the price of the one I suggested. The second one is unavailable. It still is available in my town. Also, keep in mind that a higher velocity fan may also have a bigger power draw... something you DON'T want, especially when working outdoors where electrical service can be sketchy.
Also, the amount of velocity doesn't matter. At the '1' setting, the fan I use moves more than enough air to keep me cool. On the '3' setting, you can give everyone on the dance floor an instant bad hair day. The tall one has louvres that you can adjust and you point it towards you or from the side.
I've had mine for about 4 years.
