I'm from Germany, too, and I just imported a HHKB Pro 2 and a Topre Realforce 87U (and some Filco boards) from Elitekeyboards. Considering the lack of any warranty, shipping and VAT, this is an expensive thing to do, but I don't regret it. Elitekeyboards is very professional and I highly recommend this store.
I think the Topre switches will suit you very well. Cherry browns are great, too, but to me the Topre sounds quieter and feels lighter. Very nice board to type on for hours (I do programming, too, and writing long texts all day).
A while ago, getdigital.de sold the HHKB Pro 2, but now the only have the Das Keyboard. If there was any shop in Europe with fair prices, I'd buy another Topre.
