Just picked up a Kerurig B155 brewer for dirt cheap for an office of about 40. We'll see how it goes, but the initial reception was really positive...particularly for the variety it provides. I like that it has a temperature setting, which I had previously thought was restricted to their Vue line of brewers. It joins the wall of about 5 other coffee makers, and a couple hot water heaters, most of which are in filthy shape, and just covered with scorched brew. I never used those myself...not a fan of burnt coffee. An aeropress would get like zero use here...just not enough curiosity, and way too busy in the office setting for folks to explore the idea.
