Suunto Zoop or Cressi Leonardo are both solid, basic and inexpensive. Zoop commonly show up used for $150 or less, little more in a console with a compass. I wouldn't call the interface on Suunto computers overly intuitive, but once you get used to it, really solid basic computers. Zoop was my first computer and twenty years later, its still my backup to the Terix I use all the time.
Cheap is relative, of course. You can get a Shearwater Peregrine for half the price of a Terix and that can be mounted in a console with a compass, but it has a digital compass onboard so you could just mount it with your pressure gauge if that is your preference. Wouldn't call that bare bones but its a fantastic computer for the price. This computer is my typical recommendation to students. Might be that this is what you are already diving.
