well i guess ill chime in. i work for lasersharp...
www.lasersharp.bz and no i am not advertiseing just showing you guys what i do for a living, im a printer tech.
so here are some numbers to run by you.
inkjets cost about 25 cents a page to print.
laserjets cost about 1 -1.4 cents a page to print.
ya laserjets are black and white but they are way cheaper to run.
laserjet 3015 is a nice MFC. i also fix canon and hp inkjets and i perfer canon because of there warranty. hp warranty you have to send the printer to them as canon you can bring to a local authorized dealer and its fixed at no charge in 3-5 days.
what i tell customers is to buy a nice laserjet MFC like the 3015 or the 3380 or what not. and then buy a cheap 50-70 dollar inkjet to print your color stuff on. its also a lot cheaper to print you stuff in black and white on a laser to proof it and then print it in color as you might make a mistake and your dealing with 25 cents a page.
here are some more numbers
about 50 bucks for ink cartridges and you get 300 pages per cartridge.
about 70-80 bucks for a toner cartridge and you get 3000-5000 prints.
anyways thats my .02
hope that helps.
laserjets hp all the way
inkjets i prefer canon because of the warranty, also i forgot to mention canons ink is cheaper.
