To me the question is whether the new lasers are very durable. It's easy to get a new 1200x1200dpi 20ppm ethernet laser for around $200, which considering I'll pay a ton of money just to have an older laser shipped to me, is a steal.

But man, those older Apple LaserWriters were tanks. Just keep putting toner in them and they'll keep printing. I'm not so sure about the newer ones.
