We don't know what exactly happened to the company Skywalker Jets and its promise last year to make jet packs commercially available, but here's a heads up to all of you who really want one and have the money to fund their desires: two companies are currently selling jet packs and promising to keep you afloat for at least 30 seconds.

Mexico-based Tecnologia Aeroespacial Mexicana (TAM) is currently offering TAM Rocket Belts for US$ 250,000 each. This package includes the gadget itself plus flight and maintenance training modules. It's being fueled by hydrogen peroxide and on a full tank, the jet pack weighs 124 to 139 pounds - all depending on the size of the pilot. TAM promises 30 seconds of flight.

On the other hand, Colorado-based company Jetpack Inter­national is offering Jet Pack H202 for US$ 155,000. Needless to say, we haven't had the opportunity to try any of these yet but it seems that H202 is more worth your money. It weighs 139 pounds and is capable of carrying you around for 33 seconds.

Any takers?
