Where can I find LEGO technic pieces? I love the design by me software, but there are too few LEGO Technic pieces.

Do you know somes places (in Europe) where I can find LEGO Technic pieces without buying sets ?
Directly from LEGO:


Pick a brick


Third party:


bricklink.com


bricklink is cheaper in most cases, on both you can choose and buy only the pieces you really need.
