I can say that I dont use psi products, not because there is anything wrong with them but because ive had no need too, yet. I do have a few friends that run their recones and I have seen them perform very well. I can say yes, going with a recone from the original manufacturer would be the best bet but unfortunately some have rediculously long turn around times, some have rediculous prices. If it was not for psi pricing and speed they would probably not be used as prevalently as they are. As for stealing parts and designs I wouldnt advertise that info unless you have actual proof. As for me, I have no problem with their products. If it fits your budget and you want to run it, go for it. If you find out you dont like it you can always sell it and try something else.
