Interesting, usually I expect European hardware to be more expensive. Some of those printers have been discontinued in the US, but others are still available.
The cheapest Postscript compatible I found in the US was the OKIDATA B411d 91659801 at 4169 plus $22 shipping and handling.
What would you recommend? I'm not too fond of all in one printers and a lot of laser printers come with very little memory (like the Oki I mentioned with only 64MB).
What's a good compromise between price and features?
