Interesting. I'm pretty sure the ones I bought said "new".
I just got the last batch of five of the A55F-M4 v2.0 boards. Some of them had slightly-crunched boxes, and one of the boxes, it was obvious it had been opened and re-sealed, and had a red plus or marking on the serial number label.
Maybe they are warranty returns. If so, that's pretty sleazy, to sell them as new.
Edit: Ascendtech has a $29.99 FS ECS A75 board listed, as "manufacturer refurbished", but their other A55 ECS boards are all listed as "New (other)".
