I have a Samsung CLP300 costing just under £100 click here
You can buy a toner set for about the same price as the printer (or cheaper if you buy compatible off ebay). I've just replaced the black toner cartridge for £12 click here|39:1|66:2|65:12|240:1318&_trksid=p3911.c0.m14
Print quality is OK if not brilliant but it's a great little printer for its price. You can also buy a Network version.
The toner supplied with the printer has lasted me almost 12 months of very light use.
