Hi Pete - I have got both the spokes and rims (bought before they hiked up price). They are DID but with additional stamped writing and not made in Japan , the chrome looks pretty good and I suspect they are what everyone else uses. Not used mine yet though, still plucking the courage to lace them myself (with the help of my old neighbour who used to do it years ago). I think a lot of chromers will not rechrome rims any more and they would be far more, I suspect to rechrome, than the DSS ones. Rear on K0's have a unique rounded portion but I can't be bothered with all of that 'Sandcast' nonsense. I think most of DSS's stuff is reasonable quality and he gets a good price from the manuf's and passes it on.
Cheers
Ash
