Best PK adapter for sony a7

Just curious what your experience has been. Not looking to spend $175 on the voigtlander if a $30 fotodiox will cover the image circle. I'm also not looking for any with aperture controls, since most of the lenses I'm using have aperture rings.

Although I do wish techart or metabones or whoever would just invent an Auto-Aperture/AF adapter. Any engineers in here want to give it a shot?

The adapters are just simple hollow tubes, so it all boils down to build quality. Whether or not you care for an aperture ring, it's really hard to go wrong with a fotodiox!

No aperture ring:

The cheap $15 ones on Ebay are fine and as long as hey allow infinity focus, which they all should, you are fine and good to go.
