Printer Supplies

I'm buying a printer and when out at lunch today I dropped into one of those shops (that shall remain nameless) that refill cartridges to get some advice.

Q. Which is cheaper for printing large amounts of black and white A4 paper, Laser or Inkjet ?
A. You will have to replace a cartridge every 200 sheets for an inkjet, every 2000 for a laser, much cheaper...

I think this could be an exageration but you get the point.

Q. OK, if I have have to get a colour inkjet what would you recommend ?
A. Whatever you do DO NOT get a lexmark, they are crap. Get a HP or Canon printer, the cartridges are cheaper and easier to refill. Some other manufacturers are incorporating fuses into their cartridges, when the ink gets low they blow the fuse so you can't refill it. For other types a certain percentage of any manufacturers cartridges will NOT be reusuable, if you get a HP one they will have a replacement because they are so common and will fill it for you for the same price...

Q. What about the Dell printers
A. Oh god no, they are basically rebadged lexmark printers, stay away... They are cheap for a reason!

So looks like I'm looking for a HP laser printer...
