I would get 550EX and <Sigma 500 Super or another 550EX>, ST-E2 and OSC2.
Why 550EX level flashes? --- They have manual mode. Why Sigma as a second flash? --- It has dumb optical slave mode so by connecting the 550EX on camera (with or without OSC2) I can get wireless slave functionality in manual mode totally without any preflashes (set the master flash 'master' switch in manual position and flashes in 'M' mode). Having preflashes (either for exposure measurement or slave control) makes using flash meter error prone at reduced power levels (although using ST-E2 helps here). Sigma is also cheaper. Why 550EX as the main flash? --- Better quality, works with "every" Canon camera. Why ST-E2? --- More freedom. I prefer to *not* use on-camera flash if possible. Not tied to the OSC2 cable length. Why OSC2? --- ST-E2 does not have a ball head so by using the OSC2 it can be pointed in any direction. Can also be moved behind the disturbing objects (e.g. outside a hide/blind when the flashes are outside).
