You may find Naniwa Professional (former Chosera) stones with
knivesandtools.de
I have yet to see better prices in Europe.
You will need at least a medium-coarse like the 800 and a medium-fine one like a 2 or 3k. The end result will correspond to 1200, 3 and 4k according to JIS standards.
See as well their Belgian Blue and Coticule. If you use a very fine stone only for deburring a small one may be an unexpensive option.
Getting stuff from outside the EU involves import tax, local VAT and handling costs.
The MAC Galley suggested is an excellent option, and great value.
You should be able to maintain it for a long time with a Naniwa Pro 2k only.

Thanks for your reply I already ordered two shapton kuromaku stones a 1500 and a 5000 one. Those were suggested by on of the other members they are currently in Tokyo so they gonna take a while to arrive.

Great stones. The Shapton's grits are a bit different from the Naniwa's. I guess yours will be equivalent to JIS 1200 and 4k.
