I am selling a Mitsubishi MTA-100 Operator interface that is in very good condition for $300. The unit works well, I just no longer use the automation cell that it is used on. The price does not include the emergency button, power button, nor plexiglas that's shown in the attached picture. I do stand behind this unit, and if you were to receive it and it doesn't meet your expectations within the first 10 days, I will 100% refund your money. I will also ship this unit at no cost within the United States 48 states (if Alaska or Hawaii - I may need to add some shipping costs). If you are outside the US., I can calculate shipping costs if you are interested. At this price I believe this would be a great purchase as a spare component, typical retail is anywhere between $800-$2500. I will except reasonable offers as I no longer have a need for this unit. Please let me know if you have any questions.
