I found a Tree Journeyman 325 for sale and I was hoping to get some input. Judging from the user manual I'd guess it was made around 1994 (the last revison date). It has 2 known problems:
1. The monitor doesnt work
2. It has a z-axis encoder error
I think the monitor just went out because the guy said that the screen shrank horizontally and vertically over time before it stopped working. Other than that, they say it functions. It has the dynapath delta 20 controller.
