Big thanks for all the posts! This is very helpful I'll try to answer all the questions you ask.
I'm currently working on my projects with an analog Hasselblad and enjoy the film-photography routine (besides, if you want to find out what I'm shooting check my blog http://portretulicy.blogspot.com). What is more, actually the only lens I use is 80mm. I started working on the project about suburbs last summer with Mamiya RB67 and 50mm lens, but lacked the movements and after a while stopped. This project is something private, which may or may not turn into something bigger, therefore the quality of the image is important. I perceive it as a kind of sociological study. For sure the web-size images are not my target, rather the prints Perspective correction on a computer is a tool I sometimes use, but I don't want it to become the method. Moreover, movements would not only correct the perspective, but enable me to, for instance, change the proportions of the fence and the building behind it on the picture. 50mm on RB67 was often too wide, I could easily get away with something narrower (65? 70?). So, after last year's experiences I decided to seek for a LF.
Am I right to think that your suggestion is a monorail with a wide angle lens (let's say 65mm), as this kind of a kit should work better than a field camera? Would it be possible to buy such kit with the lens and a film back with $1000?
Emmanuel, this is a nice series, inspiring! Greetings from Poland
