Any instances I've heard of people stripping out lockring threads have been related to improper setup, not cheap equipment (except maybe some buzz about formula lockrings). Make sure when you get a new hub you tighten the cog with a chainwhip and the lockring with a lockring spanner or lockring pliers. Go mash up some hills after you get them both tight and avoid skidding or intense backpressure until you tighten the lockring another time. There are plenty of guys here that ride formula hubs (i believe thats what origin 8s are) and they are regarded as solid entry level hubs.
