go to ebay and take a look at LED power supplies. There should be about a thousand or so. Here's the link for the first one I found:

And, that was just a basic search. Alibaba, sourcingmap, etc have many, many of these at prices that made my jaw drop. I have two that I bought (quantity 1) for 3.95 free shipping. If I bought ten of them and redeemed the coupon I got I would have gotten them for about .80 cents each (still free shipping).

Well check out what I bought a few days ago in the power supply regulator section of E-bay. Five buck switching regulators for $1.53 each. At that price I bought 5. Plus free shipping :wink:
