Cheap should not really matter too much as long as it is a solid build and you are sure the electronics you are hooking up support the local voltage. I have had great experience with http://www.dealextreme.com/ in the past, however they standard shipping can take a little time, they do have expedited shipping. They have unbeatable prices. If I had to pick one up locally however, I know I would go to Frys Electronics for an inexpensive solution.
