To me, the most important part of getting a sharp photo besides the lens used is the tripod. Like Jeff said, the Bogens he mentioned are probably the best buy around for stability. There are other tripods out there that are more stable but at a greater increase in price. I use an older Bogen 3221 myself, but I am to the point that I want a more stable tripod with greater vibration dampening. the weak point in my current setup is the tripod head (bogen). I am going to replace it with a Markins, Kirk, Arca Swiss or Really Right Stuff Ball head because my technique now surpasses the stability and roughness of my current ball head. I have to photograph in the wind and I have had wind gusts litterally knock me over onto my side from a crouching position. The larger Gitzos and Berelbachs stand up to the wind much better than the Bogens. So it depends on how you want to buy. You can spend a little now and then spend a lot more latter on the upgrade, or you can spend more now and get the best and save money in the long run. The tripod should bring your camera slightly higher than your eye without the center post extended or you will find neck and shoulder fatique from slouching down to the tripod. If you photograph flying birds, you want a higher tripod so that you don't slouch as much when you raise the lens. A higher tripod shrinks in height when you are on uneven terrain. People who use the shorter tripods tend to hate the tripods because of the above considerations.
