The Plaubel Peco uses the same optics as any 4x5 camera, I have a 5x7/ 13x18 Peco III.
Until recently I had a Makina 67, I sent it to Plaubel for a service (430 euro) put a roll of film in shot half of it then dropped the camera wrecking the range finder and body.
My Peco III monorail goes back to the 60's I believe and it still locks solid like the day it was made. I had a Linhof Technika for a time, different type of camera I know, I much prefer the build on the Plaubel.
One other thing about buying LF at the moment, it's holding it's value much better than my digital disposable Canons. Oh and so nice to buy a lens and not wonder if it will work as it should or be sharp in the corners. I use a late 1800's brass barrel lens sometimes, made for 3 1/2 x 4 1/2, stopped down to f64 and beyond it covers corner to corner and is pin sharp.
I also have 305mm / 12inch Kodak portrait lens. My other optics for it are the usual Schneider Symmar's.
There is one on e bay http://cgi.ebay.com/Plaubel-Peco-Universal...125152004r20726
It would be worth checking that the back takes standard 5x4 DDS. My 5x7 took a Plaubel slide, I had to spend another £200 ish getting a standard 5x7 back from the factory.
I love those red bellows, isn't it beautiful ?

If you fancied a 5x7 there is another and it has the normal DDS back on it
