They don't show up on ebay because shipping is more then they are worth and don't sell. Try the local recyclers, they should get thats stuff in once in a while for scrapping.

You should look for an old Apple laser that still has cheap toner available, or an old HP laser with mac printer port interface. I use a HP 4si and a 4/600 PS for my old mac gear. I have seen other old Apple lasers from time to time but never bothered picking up another, just don't need them and they take up space.
