I've been using a Bogen (I think now they are Manfrotto) 3021 tripod with a 3047 head (this will easily hold a very heavy MF camera and has built in levels). It will get you as low to the ground as you're likely to need and will extend up to 7+ feet. The legs splay out individually--great for uneven, rocky ground. You can invert the center post. There's another attachment you can buy that let's you hook the camera onto the side of a leg (the tripod leg, not your leg). You can spend even more money for a focusing rail for macro shots. It's an extremely well built system. I can't compare it to other comparably priced tripods, never having used them. But after using inexpensive tripods, it was a sheer delight!
