Well, I feel pretty alone about this hobby around here. There's a number of collectors/mame-builders here but most seem to be pretty quite (probably language thing).
Almost all my parts and stuff come from the US. It is indeed great that the rate is so low now

But this also shows that the US market is a lot bigger for this stuff. F.I. try to find a real (CGA) arcade CRT monitor here. Good luck, and be sure to have a big wallet of money ready. (F.I. Suzo is not selling them.)
They also indicate videogame parts are not a very big business for them anymore. From the look of the Dutch equivalent of Craig's list, there's a lot more pinball fans than (classic) videogame fans around here.
I reckon that the fact that we live in a small country and that the average home is smaller (or at least, doesn't have a basement !) over here is also playing a role.
Most people around me (family, friends, colleagues) are really surprised when I talk about my hobby. First thing they say: does your wife allow you this ?..........
