already got wireless triggers and a full strobist kit with umbrellas and all that. good thing is with the new ring light i wont need any of that besides maybe using the 430ex as an optical slave off the mr14ex ring light to flash the backroundAlso consider getting an IR trigger...like the ST-E2...for the 430ex
i use manual focus for macro anyway and would only be using live view for macro. only thing i use lcd for is checking the histogram fro exposure and in the future to check focus for macroNO DONT GET THE 40D IF YOU CAN GET THE 50D reson being the brought out the 40d to early thus not haveing the proper capabilitys live view is usless in the 40d coz you have to manuel focas pluss the lcd resolution is very poor it makes you think your pics are blury not sharp !!! when they realy are !!
