probably a lot of anti memphis from people who have trolled forums and not actually used the product. as far as i am concerned memphis is one of the better mainstream companies. They make a quality product that is built to last. I personally obtained a 143.4 with 1 15 mojo quad coil on 2k (def wasnt getting 2k with stock electrical). Dont get me wrong there are better subs out there but if you dont mind used equipment i wouldnt suggest buying from a dealer as they are pricey for what you do get. But if it was floats your boat then go for it, just do some research from people who actually have used equipment you are interested in and make a determination from there.
