I have the B87 package and love it. I also have the L plate because you still need to mount it to the camera. As far as scratching the camera, RRS stuff is SO well machined I don't think you'll find any sharp corners on anything they make. What amazed me is how light yet strong this stuff is. They're not inexpensive for a reason.
The RRS bracket is well made just like all their stuff, and fits into their modular system. For instance if shooting with a telephoto lens that has it's own tripod foot, you can mount the bracket to that.
The biggest downside other than price is weight, as it is most definitely not a lightweight rig. If you're shooting handheld I think it's something to consider, as pro-level camera body + bracket + flash plus decent size lens can be pretty unwieldy and tiresome.
I have the RRS Perfect Portrait bracket and think it is great. It does not scratch your camera because it mounts to the L bracket that they sell. Very easy to use in both horizontal and vertical orientation.
I have the RRS wedding flash bracket. http://reallyrightstuff.com/flash/04.html
It's not cheap....on top of that you'll need an L-bracket to attach to it.
I love it though. It folds nice'n flat and not as bulky as other flash bracket I've seen. The portrait perfect is too large and bulky for what it does...
I can send you a picture of my set up if you're interested.
D3, RRS L-Bracket, RRS wedding flash bracket, SU800, SB800.
I have both the one you mentioned (PPP w/87B) and the Wedding Pro Flash Bracket (WPF-1)
If you are already invested in L-Brackets either is the way to go. They both have their pros/cons.
PPP: con: Heavier, bulky
pro: QUICK flip to Horz/Vert.
WPF-1: pro, light, compact, slightly quicker lens changes
con: a little slower int he flip AND if you are bouncing you need to re-adjust your flashhead with the flip.
With that said I tend to use the PPP 75% of the time because I am lazy and I really like the quick flipping and don't have to worry abotu the flash head angle.
RRS makes awesome stuff. There will be no scratching of gear PROVIDING you take your time when installing the PPP over an installed lens and changing lenses with the PPP already installed.
Also, if you go with the PPP, get the 87B or bigger. I started with the 85B and found it to be a little con constricting for zoom/focusing with the larger lenses, where as the 87B is a perfect size/weight/height ratio.
I have the RRS Perfect Portrait Package: B87-B. I use SC29 to connect. It is a great set-up. Here is a shot of the heavier (solid) B87 bracket. They accepted it back for a generous trade-up to the lighter B87-B:

The bracket is typical RRS engineering and design; scratching will not be a concern.
It's their choice! They control sales, no middleman markup and they stand behind the workmanship. Considering the quality they demand(VERY HIGH), and the relatively low volume/high cost to manufacture, there really is no incentive for them to do anything other than web sales.
