Excellent advice! There's that struggle between the rush of excitement at being able to buy...and the patience needed to research and study your product before forking over the cash. Fortunately, I have to wait at last a couple of weeks, if not longer (tax return, don'tcha know)...so I have plenty of time to research.

Good advice about the lenses vs camera investment. How interchangeable are the lenses? Can you mix brands?
