Yep, not after hundreds of euros for the whole system.
Anyway the part that bothers me is the shipping time more than the money. Usually I can find these devices only on some internet shop that if I'm lucky is in Europe. In this case, I have to wait from 1 to 2 weeks before getting the package.
If the place they send the item from is USA then... eheh, maybe I could get a solder and some instructions and try to make my own device before the package gets to my door.
Anyway thanks for the info, I'll definitely look in that direction.
