In another thread, I mentioned the 13' impacts. I don't know if the PCB's are best/worse than these. The impact brand has worked well as a main stand for me. I think you mentioned 2 Einsteins being purchased in another thread. If you're planning to use an Einstein as a boomed hairlight, I'd strongly suggest putting your money towards only 1-13' Main stand, 1 small dedicated background stand, if needed, and then put the savings of the other 13' light stand into an Avenger or other highly recommended heavy-duty boom stand. I have a popular low-cost Impact Boom stand and I'm nervous with it holding a speedlight and 24" Softbox. I would never mount an Einstein on a cheap boom stand. Look through the recent threads, there is plenty of advice on some heavy duty Avengers...which will be my next purchase.
