Amazon claims to have them, but they may or may not. I ordered a Centos from them last year. It took two weeks + and IIRC was drop/packet shipped from Taiwan. I tried recently to buy another set, but they sent me some cheap stamped steel derailleurs instead. I took a refund rather than a return, thinking they might not have them in real life anyway. The R10 may be easier to come by. Some online shops have them.
Maybe SunXCD has some sort of exclusivity deal? No one sells the Gran Compe ENE derailleurs either, which are a rebranded Arsis.
I do notice that the SunXCD derailleurs have some small aesthetic differences. The outer plate has a different shape. The jockey cage is different and custom. There are other subtle things here and there that seem to be unique to the SunXCD. Overall the industrial design is IMO more tastefully done than the MS versions. Whether or not that is worth the upcharge is going to depend on the buyer.
