Mike: There are a bunch of factors that could impact the value of this eleven year old press. You should start with identifying the total number of impressions on the press, it's service and maintenance history, and condition of the center shaft carousel bearings. A press this age that has been used in a small job shop environment that averaged 1,000 prints per day could have 2.5 million to 3.0 million impressions on it, while a unit operated in a high volume production environment could easily have three to four times that many impressions.
There's a big difference in the value of a press with 2 million impressions versus one that has 10 million or more. Assuming that the press hasn't been printed into the ground, that it's been well maintained, and there's no slop in the carousel bearings the next issue to address is to contact Workhorse Products to confirm that the PLC Control System is still viable and being supported by the manufacturer. It's a risky business to take on a press of this age if there are any questions regarding support for the control system.
Anyhow if the press is in good operating condition, and manufacturer support is available a ballpark value for the Press and Flash Cures could be in the $15K - $20K range
