Depends if you are the type to succumb to GAS (gear acquisition syndrome) or not. A Nikon D7000 or its Canon equivalent is enough for pro quality work (and are probably less than $1000 at this point) but for some guys only full frame will suffice -- even though most viewers (even pros) are unlikely to tell the difference. If you're that type, a Canon 5D2 or 3 or even a D800 may be what you wind up getting. I would say the lenses are far more important: avoid getting a kit zoom in favor of a decent 50mm equivalent. There again, some people seem to need the top of the line, but even a $100 50mm is more than your skills are likely to ever surpass.
