Cullen Cables have worked for me and I never have paid more than $130 for any of the several that I am using in three systems.
Also, +1 on the somewhat misleadingly named Counterfeit Chinese Cables thread. There are some Chinese non-counterfeit cables discussed there. I haven’t yet tried any of the power cables mentioned in that thread, but, after reading the thread, I did buy a Chinese Viborg XLR set for $80 that is impressing the hell out of me. Today, someone has posted in that thread that he bought a Chinese power cord at Amazon for about $40 and that he likes it better than the $500 cord it replaces. It’s a gamble, to be sure, but there are so many gambles in audio today, aren’t there? I have no particular use for a power cord right now, but, for $40, it’s a chance that I easily can justify taking.
