I'm not sure what type of mount Olympus uses (Canon, Nikon or it's own) but my vote is for Canon. I work in a pro photo lab and most of the movie photographers use Canon and the images look pretty good. I haven't heard very many complaints but I'll try and double check for you. Most of those guys shoot in RAW format.
If you want reviews and opinions, here are 3 very good sites to start with:
http://www.dpreview.com
http://www.robgalbraith.com
http://www.luminous-landscape.com
The first site has very detailed camera reviews including sample images (noise at various ISO levels, resolution charts, sample images, etc). Very active forums as well.
The second site has some info on camera's but not nearly as much as DP Review. Forums are also very good at this place and I think there are some Canon people who post there on occasion.
You'll find some reviews on camera's and lenses on Luminous Landscape.
Assuming Olympus uses a Canon mount and you can afford a full frame sensor camera, you won't have to worry about your 50mm lense becoming a 35mm on the digital camera (or however that stuff works).
If you find a used Kodak 14n, I'd avoid it. I wouldn't buy any Kodak, especially this one.
Fuji S2 used to be good for noise levels but I don't know if that's still true with some of the newer camera's. You can see noise comparisons on DP Review.
I can also give you a list of software and sites for all kinds of post-processing fun if ya need them.
Speaking of photo, we've got a big Durst, rail mounted enlarger we're giving away for free.... just have to pay to haul the thing away.... and I can't find anyone to take it! Know anyone who wants it?

Might have a big floor one too but I'm not sure if it's spoken for.
