Always maintained under Stratasys service contract until recently. Was working perfectly at time of shut down in June (long term shut down procedure performed properly with both support cleaning fluid and material cleaning fluid). I have owned and used this printer since 2015 and it has been a spectacular printer. The only issue is that you will need to supply your own computer, as the computer for this instrument has a bad power supply. Ideally, you already have one of these and just want a spare full of working parts.
Update: Recently had a question about the # of hours on the machine and when I went to turn on computer and check, I discovered the bad power supply on the computer. I'm now selling this as for parts, not working because of the computer issue and because I can no longer verify operation without a working computer.
