Hi, I currently use a Nikon D40x with a Sigma DC 18-200mm OS HSM as my primary lens. I have alot of older lenses that I occasionally use, but those older lenses were meant for my father's Nikon 35mm film SLRs. I am looking for a flash unit as well as a tripod that is easy to operate. The pop-up flash on my D40x is definitely not great and my current tripod seems wobbly and it is really hard to adjust the 'tilt' along the 'axes'. Please advise which flash unit and tripod would be the best bang for the buck. I also might plan on getting a D300 later on. (So hopefully the accessories are would complement both the light D40x and the heavier D300). Many thanks in advance, and Merry Christmas!
