Price doesn't bother me. Trying to make good photos is a pain, lugging equip around, lens, filter, flash, gel selection ... I've held off buying a PW system because it's clunky and doesn't fully integrate with my cameras capabilities. The Canon system is clean, simple and will work flawlessly. Even gels - I hate stupid tape or velcro solutions, finally there is a nice holder and a clean way to manage them.
I saw a comparison somewhere of the new Canon against some 3rd party wireless, and the Canon came out $75 more expensive for a three flash with ST-E3-RT solution (and that was before the ST-E3 last minute price drop).
So I preordered three flashes and the ST-E3-RT.
In what way does the PW not integrate with your system?
