Sorry this is both subjective and out of date, but you asked for experiences.
Have had two mono laser printers. the first a fairly cheap Epson which did all the things I had hoped for except the paper transport. This was abysmal particularly as it grew older, seemingly dragging a bunch of paper through at random.
Currently have an HP P2055 costing about £160. This has behaved very well and is fast and as sharp and shade-accurate with monochrome pictures as any I've seen.
It is no longer in production! You may have more useful help it you could give your price bracket and expected workload.
