I have a Fotodiox and a Fotasy...I like the Fotodiox Pro as it comes with a tripod mount attached however, I sent one back as the camera did not sit 90 degrees to the baseplate, they were great about making sure I got one that did. The advantage of the mount on the adapter is that you have full access to the batter and card with the camera still mounted.
I'm using a Fotodiox adapter that I purchased a few weeks ago. There is an "aperture ring" built into the mount, though you can't tell what aperture you're at besides the obvious fully open or stopped down. I've tried a few of my nikon lenses (35 1.8, Tamron 28-75 2.8) and they all work beautifully.
