I have three of these...
http://www.dealextreme.com/details.dx/sku.1320. They are $ 2.78 (includes s/h) and they work like a champ!! They are shipped from Hong Kong and take about 7-10 days to arrive...but well worth it. I bought one about two months ago..still using it, and it rocks!! So I bought a few more for stand bys.
