portable lightweight 5V power supply that can handle 2+ amps

Hi all,

I'm looking to make a project using an arduino and one of these type of LED strips: http://www.adafruit.com/index.php?main_page=product_info&cPath=37&products_id=306&zenid=4e40aa707a2c9e790cf7de8f34ad2452

One thing is that they can use up a lot of current, I don't plan on writing my software to allow 2+ amps but... never design your hardware so that software can blow it up! I am hoping to use a single 9V to power everything so need a power regulator to go from 9V to 5V. I assume the one on the arduino cannot handle this much current. The ones I've used in the past handle 1A, are there any beefier ones that arent too expensive?

Can anyone refer me to a good one? Preferably something that will not use up too much board sapce.

If you look around the RC model community you will find references to a BEC or UBEC -- battery elimination circuit. These are compact light and efficient switch mode power supplies. You will find ones that can work from 9V up to 30+V and that supply 2A to 5A of 5V.
