well, i mean, it all comes down to your needs. if you'll be using a copire, fax, scanner, printer a lot then of course it's definitely cheaper. but if for example, you'll only be using the printer extensively and maybe once in a while the fax, then don't do it. then again, prices have dropped so it really is up to you.
Laserjet will give you better quality pictures definitely that's why they're more expensive. however, if you're not gonna ba doing a lot of graphic work and printing professional pictures, then in my opinion an inkjet should serve you fine.
