Best wall chargers?

[KingHuds]

So I somehow just lost my charger that came with my phone and don't really wanna pay the $30 or whatever it is for a replacement, what are some good alternatives to charge a 3GS?

ebay has them cheaper.

Note that the $30 wall charger also comes with a USB cable, if that changes your mind at all.

I've used chargers from this firm, they seem identical to Apple's own at a fraction of the price.

An example is :- http://www.dealextreme.com/details.dx/sku.27524

but look at the alternatives with US/UK/Eu etc plug patterns.
