I bought one retail. It’s actually a pretty good printer. Refurb on printers would worry me though. The toners carts are sickly expensive, but there are alternatives, just don’t update your firmware after you install (I’ve been told) or it might stop working.
I can send print on 175g card stock, but not in the manual feeder.
It did basically crash hard one day and I had to go through setup again and since, cloud printing hasn’t worked.
