My main body is a Canon 20D, but I also have a Rebel XTi as a backup.
Lenses are all over the place, with my main ones being:
Canon 50/1.8 (with macro extensions)
If I feel artsy or weird I also play with some 'cheap' lenses I have:
Lens in a Cap
Japan 500/8 Mirror
I hope to get the new MkIII, but may settle for the MkII
