Most industrial listings do not state condition — treat unstated as unknown, not as new. Across 666 comparable parts across the index, used and refurbished units are listed at a median 83% of the new price. These are asking prices, not sold prices, and the spread around that median is wide. Ask the seller to state condition in writing before comparing quotes.
