Still going strong with my 4x5 Bender that I built from the kit back in 1991. Bought a 210mm Nikkor to go with it and have been using it since then.
Just last year I forked up some cash to get a RODENSTOCK 135mm f/5.6mm APO-SIRONAR-S on ebay and am always looking for opportunities to go out and use it.
The Toyo 45CF seem to fit your needs. However the used prices appear to be higher than the new price. This was my first LF camera and I bought it new from B&H way back in 2002 when they first came out. This is a great camera for backpacking and you don't need a heavy tripod for it. I use a Gitzo 0 series with it. I now have SIX (I can hardly believe it!) ToyoView LF cameras: 3 fields (AX, CF, MII) and 3 monorails (Robos, 57GII, and810G).
