Hi Game,
I am living in the Netherlands too, but bought my brand new Tachihara in the US in 2004 via the internetshop of Midwest Photo Exchange, since I couldn't find a shop selling it in the Netherlands. Yes, it cost me some extra for taxes and all, but with the current exchange rate, it wasn't too bad. The original price was 595 dollar, and I ended up paying some 600 euro or so in total.
Of course I still needed lenses, and bought them second hand at ABRO in Zaandam (
http://www.fotoabro.nl/). You definitely need to visit this shop once if you're living in the Netherlands and you really want to venture into LF. They have lot's of second hand stuff for large and midformat photography (both camera's, lenses and accessories), the only shop of it's kind I know of in the Netherlands. It doesn't look much, the out- or inside of this shop, and Zaandam of all places..., but that's not what you should be concerned about. If you really need something, go there!
Yes, my lenses WERE expensive, so a 500 euro budget is really a challenge, but I have never regretted buying all the stuff.
About the Tachihara:
There is one aspect you probably do not have thought of: you may end up spending more time in social talk with curious complete strangers, than photographing ;-)...
It is jaw dropping beautiful!!! Cherry red wood color, brass looking like gold, and you with a dark cloth over your head... When I spend 2 weeks in Siena with this camera, people were looking all the time...
Technically, it's stable and flexible enough to do it all. I only found some of the knobs to be a bit fiddly to use, but not a real problem. And yes, the first few times you wonder how it all folds in and out...
I have successfully used a 75 mm wide angle lens (Schneider Kreuznach Super Angolon 5.6/75) *without* the need for a recessed lensboard, making handling of the shutter much easier.

Happy photographing,
