I paid about $250 12 years ago for exactly what you describe. It's an HP Color LaserJet. Since it's laser, there are no clogged cartridges, the toner works forever. It has built in Ethernet, and both MacOs and Windows can auto discover it. Since it's jet direct, you can just send it PCL so there will always be drivers.
It only has three problems:
1) no WiFi (which is understandable given its age), which we solve with a bridge.
2) if you leave it on, it occasionally runs a self test/clean cycle, which set off our old house's smoke detector. Fixed this by turning it on when we need it.
3) no duplex option.
Other then these issues, it's a great machine and is literally the oldest piece of tech we own.
