Canned air alternatives

So we are looking to an alternative solution for canned air. So I am looking for input from some techies that may have used these 2 products. Each has benefits but I am looking to find the one most worth the cost of the drawbacks due to the benefit they offer and surely I have no desire to have a new decoration for my desk....

The Hurricane -

benefits ... cordless
not sure of air flow power

The Datavac -

benefits - plenty of air power
con - corded

So if anyone has experienced these products and can give pointers on their realistic usability and portability I would appreciate it much :)
