We use Brother laser black and whites for at desk printers. $50-$70 at officeworks, buy them in multiples and just throw them out when they run out of ink (it's about the same price for ink, we never have breakdowns because they are replaced a couple times a year).
have a mid range brother laser colour multifunction in the planning office, that one we replace inks and drums on. The planning firm is fairly much paperless and we really don't print much.
Have a high end fuji xerox system in law firm. We aim for paperless inside the law firm but still need to print hard copies of many documents that require registration or safe custody, off the plan contracts can be 70 pages etc so still print a lot.
The biggest benefit of this machine is the very large capacity automatic document feeder. These ones cost thousands so way outside of your budget.
If you don't need the document feeder under $100 for a laser should sort you out.
