What is your budget Morten? If we know what you can afford, we can make some pretty specific suggestions. For under $1000.00 (US) you can easily get a complete kit of camera lens and tripod. A Burke and James, Calumet C1 or Kodak D2. Lenses such as a 12"/300mm Commercial Ektar are very affordable although they may require a cleaning. And a surveyors tripod works nicely, although you have to get a thread adaptor to use the common 1/4" hole found in the older cameras.
Older cameras are less expensive but are heavier and have less movements.
Newer field cameras such as a Wisner, or Canham can be found on the used market but expect to pay between $1500 and $2000 for the camera alone. here you get more portability, better quality of construction, more generous movements and in some, but not all cases a lighter camera.
Here is one on Ebay that would really be perfect for what you are suggesting.

This looks from the pictures to be in really good shape. Masterviews are a little heavy, but perfectly good for both field work and studio. I personally consider Master Views to be a very "cool" camera. But it will probably go for about $1500.
Here is another one on the opposite end of the used scale.

This camera looks pretty rough. It might go for as little as $250 US. If the bellows are light tight it would be a good starter camera. A PIA to transport in the field but adequate for studio work. But if you don't backpack and work mostly short distances from the car it is perfectly good for landscape.
Of course there is the ubiquitous Deardorf:

I imagine that this will go for around $1600. You never know with a Deardorf. Sometimes the prices are inflated by the "cult" of Deardorf and reflect a collectors metality that I don't really understand. Other times they go for very reasonable amounts.
Then there are the Sinars, which always are on Ebay as studios and pros dump there LF gear for Digital. Sinar of course (and Arca Swiss) are the standards for precision cameras. Overkill for what you want to do or for that matter, 90% of us. Also not portable and if somethng critical breaks, you need major dollars for parts or repair. Here is one on Ebay right now:

I don't really know that much about Sinars, but I imagine this camera sold for $6000-$7000 US new.
I don't know any of the individuals selling these cameras, just provided the links so you can compare 4 really different used 8x10s. And don't take my price estimates as gospel. They only reflect what I consider to be the current trends on Ebay.
