I think I will order them from China indeed. And will add some more cool stuff to the shipment.

A friend of mine is bringing a couple of huge super strong magnets for me from somewhere soon. The kind that cannot be flown on airplanes and can fly to each other across the room and kill people I think. That will be fun.
I also need to get some gallium to play with. And now I have to add LED's to the list too.
