I have a PMDX-125 used for a month and replaced with a PMDX-126 to get the probe feature added with the move to the PMDX-126. It is "as new". This is a marvelous board, well built, excellent documentation, check
http://www.pmdx.com/PMDX-125 for info.
I will sell it for US$140 shipped USPS Priority to US.
