I look at it like this, the best that is closest to you... If something shits the bed, its a bitch trying to send it back. I had an art carr back in the day in my syclone and was very happy with it, but by todays standards i haven't herd great things about them. Pa Performance - they stand by there warranty but you have to pay for shipping... Which can be a PIA . Dynamic mixed reviews but in driving distance, and Freddy Brown ( which I have now, and in LI) is supposed to be one of the top companies for an aod and also lyntech (spelling). If you want anything GREAT get ready to pull out the cash, shit adds up quick.
