The R3S is basically the R2 with a new name. I've bought two R3 keyboards, a regular PC version and a Mac version. I think they look nicer than the R2, and the software is far superior, but they don't feel as nice. They use fewer screws than the R2 to hold the PCB and plate together, and they sound and feel worse than the R2. Mechanicalkeyboards.com sells the R3 in the US. I don't know if they ship to Europe, though. The R3 lineup has also been simplified. They're almost all silenced and uniform 45g, so there's no PFU limited edition anymore.
