There may be stores in that area, but it's not likely.
The same as Swiss meter-guage, there not a lot of modeling in the States for either scale/guage. I also model in regular HO, but still no European equipment I would pay the prices they are asking for here in the States. I save about 25% by ordering direct over the gouging US dealers charge, even with UPS Global Express shipping.
I order direct from Germany when I purchase for my railroad. Many others in OO scale order direct from the UK via Hatton's or another shop. I order from three different shops in Germany.
