Surly must think Wippermann/KMC/YBN/SRAM deliberately use lower quality materials and processes on their 1/8 chains compared with their 3/32 ones. This seems unlikely.
Also, most of the clever stuff going on with 3/32 chains is about making a compromised design (bushingless) work, and making it jump off the sprockets as easily as possible. These are not things which recommend themselves to the singlespeed user. The latest and greatest development is applied to 10 speed chains which don't work with normal 3/32 single sprockets anyway.
Finally, expensive chains are not superior to cheap ones by enough to overcome the fact that you can replace the cheap one more frequently. The rest of your drive train will last longer if you use three £10 chains than if you use one £30 chain over the same cycle.
