Mael, Have you considered a Pentax 645? They are great cameras with some very sharp lenses and the first 645, the manual focus cameras, are fairly inexpensive. I have used one for the past 10 years and have been very satisfied with the reliability as well as the quality of the images and 15 shots to the roll of 120 film is a good thing. I used a Pentax 67 for many years before my 645 and was very pleased with the image quality, but it is considerably heavier than the 645. The 645's meter is center weighted almost a spot and was very accurate as well. Check it out.
