Personally, if you have the money I'd recommend Amedeos adapters as they are very well made and are going to last you forever. They will also retain their value if you ever decide to be rid of them whereas a lot of Chinese made-adapters basically sell for pennies on the 2nd hand market.
Awesome, thanks! They're a little rich for my blood at the moment, but that won't last forever. Good to know that they exist though.
At present I'm saving up my pennies for a used Sony and an adapter for Leica screwmount lenses first. I've got a decent assortment of M39 glass, but only a pair of Sonnars.
