Try the Samsung CLP-510 http://www.samsung.com/au/products/printerfaxcopysolutions/ printerfaxcopysolutions/clp_510.asp?page=Features

Came with three year on site service warranty and duplexing. I learnt the 500 has a xerox 6100 engine in it and verified this using the 6100 driver. I have mine plugged into an airport express and it is sweet. I have tested the warranty - I snapped the lugs off inside the fixer cartidge - a gotcha you should look out for and apperently frequently done by first time buyers and major servcie call out for machines under warranty.

Consumables Black cartridge is 700 pages. Fixer/drum is 10 k or 15K . I work out my wife will use 14 reams of paper in 2 years which is equiv to 2 sets of epson ink cartridges. roughly 500 dollars.


While we are on this subject , the laser cartridges will do lot's of pages,

BUT the initial supply is much less. That's an industry standard .. they all do it.
For the CLP-510 this is the data :-

Black toner : 7,000 sheets @ 5% (starter: 2,000 sheets)
CMY toner : 5,000 sheets @ 5% (starter: 1,500 sheets)
Drum: 50,000 images ( 12,500 Color)
ITB: 50,000 images (12,500 Color)
Waste toner: up to 12,000 mono pages @ 5%

Have fun
