Two things I don't like about the 600 RT is that with the 7D (or any camera before 2012) you cannot use the camera's menu screen to set radio transmission and you are limited in the sync speed (1/125th for 7D) with radio transmission.
I'm using 600rts with the 60d, and it works @full x-sync speed and radio transmission just fine, at least so far, though I've only got the set for two weeks. And I'm ok with using the flash lcd to set things, I'd do this anyway rather than search for a submenu item on the camera lcd.
The one thing I'm really annoyed about is that only 2012+ cameras can use group mode w/o any apparent reason, the 60d can use radio, and you can even *set* the group mode function on the flash but the camera keeps resetting it - sounds like a Canon marketing quirk to me, surely this could have been fixed.
Whilst the pre 2012 bodies will work at original sync speed, they don't offer true full sync via wireless, if you look at the bottom of your images shot at full sync with wireless you will have a band, like this test shot of a white wall (ignore the top right corner). Might not be so bad with crop cameras but with a 1Ds MkIII I get this at 1/250 with wireless.
More often than not it is not a problem, but it is there.
As for the separate wireless trigger and older/cheaper flash setup, well it is cheaper for very good reason. The 600's are incomparable to anybody that uses speedlites professionally, I used various types of third party triggers for years but bought into the RT system and it is a game changer, even on my pre 2012 bodies. If you shoot for money, especially weddings, buy once and get the RT system, with a complimentary Einstein or two for bigger jobs.
