You guys are scaring the poor guy!

IMO, the D70 kit will keep you occupied for a long time. I am guessing that since you are using a prosumer, your knowledge of the basics of photography (e.g. aperture, shutter speeds, ISOs, etc) is not 'there' yet.

So it is probably better that when you get the D70, you spend more time learning the basics. You are not going to learn very much if you have to switch lenses and learn how to use the separate flash unit.

Since you want to take macro also, stuff like a macro lens and a tripod can come in later, but I think the kit at the moment will allow you to do flower/butterfly shots already.

My apologies if my assessment of your photographic skills is off the mark.
