That is a great price Mark, but its one of those that suffer as described, and now 20 some years old. That may be about what its worth. 4 channels is nice, and needed to calibrate a DVC-PRO video tape deck. The only other 4 trace I know of is a Hitachi, we have one at WDTV, but its triggering circuit is best described as lame.
