Could someone offer plain-English differentiation between the SB-27 and SB-28 speedlights? I'm thinking of saving a few bucks by buying the SB-27, but want to make sure I won't be giving up anything I really need. Also, have any of you ever bought a flash gray market? I've never had problems with lenses gray market, but I'm a little reluctant when it comes to speedlights. Jim Laubach Bethlehem, PA [EMAIL PROTECTED]
