I use an Olympus E-10 and love it. Its has of course got a hot shoe and pc sync so you can run all the flashes you want (I dont use either in the studio).
You can get them for under $1500 or go the E-20 now, you can get them for under $1500 as well.
I dont use the LCD on the back of the screen at all - maybe once every couple of shoots, I honestly cant make a judgement about how good the photo is from the LCD. You are better off taking a few shots and throwing them up on a PC.
The only time I would look at the LCD is if I wanted something strange with the shot composition and wanted to check it worked.
My link is in my sig if you want to check quality and I know Dean from
Planet Content uses a E-10 as well so check his site out as well.
