GH2 Best M4/3 to Nikon adapter?

[Phenixone]

Hi,
I have a 55mm macro all manual with iris ring from Nikon and I am planning on buying an adapter for the GH2. Which adapter is the best?
I have looked at the Novoflex which looks good but would love to get your point of view. http://goo.gl/BcGPo

I have a Nikon adapter from Fotodiox that was cheap and doesn't have any play, use it with a Micro-Nikkor 55/3.5

Metabones....same as the Novaflex, but less expensive. You can buy off E-bay, they're about $80. No aperture adjustment, but it has light baffles and the mounting is solid. Easy to take on and off, very well built.
