Anyway I orderd on ebay the same relay board as he is using + some extra stuff that can be usefull, sensors, cables etc.
Shipping is around 3 weeks but later I'm going to post some kind of result just in case someone ends up on this thread in the future.
While you're at it, I recommend something like this:
http://www.ebay.com/itm/400-Pcs-1-4W-1- ... 5402c60b9e
It's an assortment of resistors; 30 values, ~30 of each (total 400 pcs? Yeah, the math doesn't add up.) Anyway, I got an assortment and I'm finding that, as expected, I'm using more of some than of others, but it's nice to have the variety. By the time I run out of any, I'll have plenty of time to order a larger package of the ones that I find I will need more of. I ordered some extra 1k-ohm resistors already, but haven't touched them yet.
Note that these 1/4w resistors have fairly flimsy leads. They work in my breadboards, but you have to be a little careful with them.
Also consider some kind of compartmental carrying case for these and your other wires, sensors, LEDs, transistors, etc. Sure you can keep them wrapped in a rubber band or just toss them in a box or something, but an organized case makes it so much easier to find what you need quickly and easily. If you find the right one, you won't regret it.
...and if you didn't order any breadboards, get at least one of those also. Super-cheap, and incredibly useful for prototyping circuits. You don't need one if you're only using relay boards, but when you move on to experimenting with sensors and LEDs, it's virtually indispensable.
