I've used both and the RPMAU is worlds better for fine tuning adjustment than the RPA series.
The issue is that to adjust the RPA you have to undo screws, then move the projector a bit, then tighten the screws. This process shifts the projector a tiny bit. A very small bit, but it is enough to throw the image off again. A half degree ends up being an inch on the screen, and that's not acceptable.
On the plus side, you only need to do this once (typically) and once everything is really tightened down, it is a very solid mount.
In comparison, the Elite mounts (RPMAU) have a worm gear mechanism that allows for precise projector alignment with all bolts tightened. It doesn't shift around and it is only a couple of minutes to setup. If it ever drifts, then it's super easy to get back where you want it, but it doesn't drift.
I would say the Elite mount probably doesn't have as much adjustment, but generally speaking, you want a projector flat and most ceilings are flat, so that mount works fine. If you need it on an angled ceiling, then you just get a angled ceiling plate, and drop the extension arm straight down from it.
For what it's worth, I buy the Elite mounts from eBay and I wait for really good prices, so I've never paid more than $100. I've also gotten 'specific' projector types, then drilled new holes in the plate that it comes with to use on different projectors.
I mean, right now, this is $55 shipped: http://www.ebay.com/itm/CHIEF-RPA-ELITE-PROJECTOR-MOUNT-RPMA176-NEW-Free-Shipping-Great-Deal-/131016165351?pt=Desktop_PCs&hash=item1e812c07e7
Drill a couple of different holes in the mount and you have a RPM series Elite mount for a great price. Depending on the projector you use, you can also look at their mini-Elite mounts, which work just as well, but are for smaller models.
