A well designed bracket raises a flash farther from the lens, so that there is less chance of redeye.
A well designed bracket keeps a flash over the lens axis so that there is no visible and distracting side shadow.
A well designed bracket keeps a flash over the lens axis regardless of Portrait or Landscape orientation.
A well designed bracket allows the flash to remain oriented up to the ceiling for bounce, without the photographer having to adjust the flash head when moving between Landscape and Portriat orientation.
A well designed bracket permits the camera to rotate CCW into Portrait orientation, so that the supplmental control buttons of the battery grip remain usable.
A well designed bracket does all of the above without adding excessive weight, without being too bulky, and without costing a fortune.
I do not know where 'expensive' is for you. For a working pro, I recommend very highly the Newton Camera Bracket
as one product which meets all of the criteria listed. RRS costs a fortune. Custom Brackets weigh up to one pound more than a Newton. RRS and Custom Brackets are pro grade products which meet all of the criteria, too, but are either much more expensive, or heavier and more expensive.
But it is >$200 for any pro grade product (Newton, RRS, Custom), which might well be out of your budget.
