Really Right Stuff pano gear is generally thought to be the most flexible and highest quality. As for value...well...it's pricey. Nothing from RRS is priced to be considered economical. With that said, the parts are reconfigurable and flexible, and that attribute makes up for the cost. You can reconfigure their pano gear as a gimble head nodal slide for macro work, lightweight cylindrical pano head...whatever. If you bought a great and moderately expensive camera like the D800, then you probably should be putting it on top of a quality head. You can save some money by getting one of the wide variety of cheaper knock-off legs and ballhead like the ones from Benro.
...and brace yourself...someone will chime in and say with your camera to get a wide angle lens and crop because you can't possibly want all that extra resolution the D800 offers. Someone else will chime in and say that you don't need to use pano heads because you can shoot handheld and/or the software is sooo good that you needn't worry so much about parallax error so just mount it on a tripod, rotate and be happy. I disagree on both counts but that is because I am obsessed with sharpness and making enormous prints with lots of foreground.
