SP looks good on price and weight
Tom Norton, who posts from time to time, had to replace the SP hub on his wife's touring bike mid-way across N America this past summer -- the bearings conked out after about 3000+ kms. So far as I know, the new hub got them home to Ohio (via Ottawa, Montréal, and upstate New York.)
The good news is that (i) SP gave them a new dyno-hub, no charge, and shipped it to the place they were staying in Minnesota; and (ii) Tom was able to rebuild the wheel in a local bike shop.
So yes, good on price and weight, and it appears, customer service. Reliability? I don't know. I have seen reports on crazyguy suggesting that the SP is reliable. OTOH, I believe its warranty period is two years, vs five for the SON.
Going back to Andre's suggestion: If 'twere me, I'd look for a built-up wheel with a SON28 hub, via an online supplier in Germany.
