To me, camera support is at least as important as a quality lens. Buy better than you can afford now, and you might just avoid upgrading and upgrading again later. Get something now which will likely hold the heaviest camera and lens which you are likely to ever use. My support system (Really Right Stuff) cost around $1,500, but it is very unlikely I will ever have to upgrade again. Also, I 2nd and 3rd the L-bracket suggestions. The camera will mount quickly and easily, and the weight will be over the center of the head/tripod rather than hanging off the side. The support system is one area in which many people skimp and I feel it is a serious mistake to do so. If you REALLY need to save $$$, I would buy used off eBay or Craig's List.
