Hey Beau, if you're looking to get into Macro stuff, and it'll help with the food and travel stuff to, pick up a set of Kenko Macro Tubes. Under $200 and they're small enough to fit in your jacket pocket. I always keep them in what ever camera bag we're carrying and they come in handy if you need to take a macro shot and dont have that specific Macro lens with you.
They can be put on any Nikon lens and turns it into a serious Macro contender.
Thanks Pat! Another thing to same my money up for...man does my list keeps growing. This hobby is becoming very expensive! ;-)
