Vic responded to my WTB post and offered me his SuperMacro IV. I was glad to get it. But, when it arrived, I was pleasantly surprised. Not only did he send me the SM IV (very well packaged), but he also included a number of opamps and buffers. In addition, he sent me another housing for the amp. I didn't know I was getting all this plus the amp.
Don't hesitate to do business with this guy. A1 in my book.
