In Sweden, you can buy large format cameras e.g. here:
www.dito.se (Cambo, Horseman, Linhof, Toyo)
You can also check
www.yfo.se and Schönherrs in Stockholm.
In Sweden, you can rent large format cameras here:

If you would buy from USA, you have to add custom, moms, freight (can be expensive) etc. If you do buy from Europe, however, you don't need to do that (it is usually included in the prices).
I'd suggest you to check out Robert White instead:
http://www.robertwhite.co.uk/
They have lots of large format cameras of different brands (Arca-Swiss, Ebony, Horseman, Toyo, Fotoman PS, Wista, Shen Hao, Rollei X-Act2 Monorail).
They are very serious, and have among the best reputation of any photographic business out there.
However, you need to check out if their prices include VAT. If I recall right, VAT has to be added to their prices (at least that is how it used to be)
And of course you have
