Hopefully a rep will see this, I just got my SP-500 back from RMA (replacement) and within 30 minutes its shaking the case, terribly loud thumping noises coming from it (as if its a bad fan), this is completely worthless. I had to shell out $15 just to send the thing in, and now this ones even worse than the original, and im sure they are going to say "send it in". Well, I dont see how I should have to shell out $15 again, I mean come on. Sorry just ranting, always bothers me when this happens.
