Dealextreme

Electronics hackers will find it extremely useful

Ever thought it was too expensive to start hobbyist electronics hacking? Then have a look at Dealextreme. They've got tons of components that you'd otherwise have to pay a lot more for in a local store.
Anything from cables to breadboards to PSUs, transistors, resistors etc. are found there. Many other circuits too, only (at this time) lacking in things like logic circuitry (74- and 4000 series) and other more advanced things. Though to get started, all the things you build _on_ can be cheaply gotten from Dealextreme.

And what's most surprising is that what you find there is often the _same_ products that your local stores have. Just marked with another label.
