Picked up a for parts/as is BK 9310 on eBay, for dirt cheap. Mainly because I wanted a three channel supply, plus I wanted a new project to try to fix. As they indicated a single channel worked, I figured there was a decent chance to revive the device. While they wanted way too much, I was able negotiate them down to $150 shipped. Received the item and while notably damaged (stand was cracked, knob and bezel missing, and dirty as all get out) after resetting the settings it worked perfectly. A new stand, bezel, and knob set me back $35 plus shipping and now it looks great! Well worth the $180 that I paid IMHO.
Next upgrades, routing sense and power out the back and adding a bluetooth TTL bridge to allow for wireless control.
