At my university we had a couple of X terminals from IBM, connecting into DG/UX, and I can certaily vouch that for early 1990's they weren't that cheap to acquire.
If memory serves me right, we had four of them on the student lab.
Everyone else could enjoy connecting to DG/UX via terminal app on Windows for Workgroups, or the older green and ambar text based phosphor terminals.
As anecdote, those big screen X terminals were quite often used to have four parallel sessions of mixes using talk and some MUD game.

They were cheap compared to the cost of the workstation they connected to. But nobody would call them cheap even if you look at the price today without adjusting for inflation.

We had like 4 Tektronix X Terminals that could connect to Sun workstations for those fortunate to have accounts, the rest was using VT terminals to a VAX. And yes, the talk and MUD use cases where popular ;)
