I would go with a 35mm SLR. Any of the classic cameras from the "Big 5" Japanese makers will do. I have owned the pro cameras from Nikon and Canon (F100, F5, EOS 3), and am back to MF only. I agree with Ole in regard to focusing with an MF camera. Also, there is just something about the cameras from the 35mm heyday (the 1970s and 80s). They were made for those who have a passion for photography. I tend to eschew the "pro" designation. My "non-pro" cameras have performed very well over the years.
Thus, I would suggest a Pentax Spotmatic SP F, KX, or ME Super. I would also look at the Minolta cameras, too (such as the XG-M, X-570, and X-700). I have an XG-M on the way. Here are the two reasons why I recommend Pentax and Minolta:
1. dirt-cheap, high-quality lenses
2. both Pentax and Minolta have a similar design philosophy--especially in regard to lenses
