hint needed!

guys, as i am from day to day more interested into photography, i would like to buy a new cam. a professional one, not a digi camera. BUT i am no professional yet, so what would be the best hint you can give me? I know Nikon is one of the best, but which one. and of course it should make great pictures and be reasonably priced. Summarised: New cam, professional one, for no professional, great pictures, not too expensive (like the ones for PRO photograpers). Is there such a ting?!? I look forward for your advices..k
