How in the world did you manage to go through 2 component groups in just 20k miles? that's only 10k per group! I've got over 160k miles on just one component group and it still works fine. And 3 pairs of wheels in 20k? I average 30k on just one wheel set and that's when I use to ride a lot in mountains.

Brand name CF forks made in china have a much higher quality control and engineering, the generics have below average engineering and very little if any quality control. In addition to all of that brand name have warranties backed up by western laws, generics claim they have warranties but rarely back them up and they don't have to comply to western laws. 5 times the cost? I'll gladly pay that much more rather than risk my limb(s) or life to some fork that could have potential problems.
