M42 to E mount adapter recommendations

[dllu]

I'm looking for a good M42 to E mount adapter for mounting a Voigtlaender APO-Lanthar 90mm f/3.5 SL on my a7R. The lens has a pin at the back so it needs an adapter with a flange to keep the pin pressed down. My current Fotasy M42-E adapter has no such flange so I will not be able to stop down the APO-Lanthar.

 

 

Any recommendations? (less than $25) I'm looking around on Amazon and ebay but, judging from online reviews, many adapters seem to have issues with wobbling, vignetting (some are designed for APS-C NEX cameras), no infinity focus, internal reflections etc.
