While money isn't a big deal, I really don't want to spend more than I need. The flash will probably be used for macro work and fill for portraits and other images where a good fill is needed. Would be nice if I could hold the flash off to the side, too. It should be noted that I use a lot of non TTL lenses, especially for close-ups and portraits, so the flash has to work with those lenses as well (older AI lenses). So, do I get the SB600 or the SB800, and why? My previous experience with flashes has been mostly automatic flashes where you just set the aperture, and a proper flash shutter speed, and shoot.
