as a Germany I have the advantage of being able to check German websites which compare costs and offers of various providers. I had actually checked through www.teltarif.de and through a Google search I came to another site which had an applet from teltarif.de running - especioally for calls to Spain. That was where Solomo cam e into the game.

All the best
