I have a polished USA-150 with some scratches on it but it works great. It is missing the power and ground terminal but I'm working on getting one. It is also missing two terminal screws but other than that this is a perfectly good working amp. I'm waiting on Robotunderground to get back to me on the terminal but I think $100 shipped with paypal fees is good for this thing. Pics will be up shortly.
