I was looking at PYC chains on eBay, and came across this Tipsum chain. They claim to be 235 grams for 118 links, which is probably close to the weight of the PYC (231 grams for 116 links).
The price is a few dollars cheaper than the PYC, and they look very similar. Obviously both Tipsum and PYC are copying the KMC X11SL.
