I have a 3KW Chinese spindle and the accuracy is more than adequate for wood. I've done quite a bit of research on chinese spindle and found that there are over 20 companies in China producing almost the exact same product. They look the same but the quality varies from one company to the next. I did a measure on mine too and it is well within specs. You'll get more inaccuracy from vibration and flex than you will get from the .002" run out in your spindle. If you are not making molds, you should be ok. PC boards should also be ok. Good luck!
