Your opinion on these

Hi,

It's a long story, but a couple of weeks ago I ended up with a large sample management system built for laboratories. There are some problems with the pneumatic systems and because it is not sought after that much anymore it's not worth fixing, but after a quick test with Tecnik's test software the robotics appear to work well.

It comes in a metal enclosure with a gas-spring acrylic hood that will be perfect for the large format 3D printer I need to build soon. The plan was to salvage the working parts and sell those I don't need to help finance the new machine. Among those I don't need might be the servo motors, I am tempted to try and use them in the 3D printer, but even though they are relatively small they still feel a bit overkill for this purpose.

My objective with this post is to ask you for a rough estimation of these part's worth, so I can sell them for a fair price for both me and the buyer.
Here is what I've got, all branded Teknic:
One servo motor M-2330-FH
One servo motor M-2330-XH
One servo motor M-2330-FH (bolted to a small gearbox)
One servo motor M-2348-FH (larger than the other servos, bolted to a gearbox) EDIT: probably a brake, not a gearbox, see 3rd post.
Four SST-1500 servo drives, one for each motor
Four TG-540 trajectory generators, one for each driver
One NC-540 network controller, connected to the trajectory generators and to the embedded computer
One SSt-3PS12-75 75V power supply that provides power to the servos

I also have a OPTO 22 i/o module with an extension board, but it was not used directly by Teknic's systems.
