Just for completeness. I bought the used SW Motech for a 1260 one being offered in the classifieds. Fits my V4 just fine, fits my value criterion just as well I do totally agree the IP infringing china knock offs should not be encouraged but I also think the Ducati tax is a bit too strong from some brands on something so basic. You pays your money and takes your choice as they say.
I got an R&G one, wasn't expensive. I don't buy crap Chinese knock offs, I'm not too keen on sending my money to a mass-murdering dictatorship...
