By hearsay I've learned, however, that they are not very popular or even known in Germany.

Maybe itīs because of the name. The German word for grandmother is "Oma".
Not actually enticing to have a pen by that name?
I read about the poor quality in a German pen forum, but I cannot say anything about it.
I have never seen an OMAS pen in real life.
Concerning dealers try and check out their website www.omas.net
Heres the two in Stuttgart that were posted on the Omas website. No web adresses given - try google
