Hi Chuck,
Since you are located so close to Dallas, I didn't know if you were aware of the Texas Instruments surplus auction that takes place every Friday Morning. It is on Northhaven in Dallas. They dispose of all types of manufacturing equipment for salvage only. It is a sealed bid auction and opens at 6:30 am They read the bids at 9:00 am. Lots af motion control, it just might be still attached to a 3000lb camera. They regularly dispose of functional robots by their scrap weight. Shout at me offline if you want more details.
Take care,
