3-in-1 Printer - Scanner - Fax

I am thinking of getting a new scanner and printer, however because of space requirments I would prefer to get a 3-in-1. Has anyone had any experience with these under linux? If so any advice recommendations? I expect that some of the frills are lost as they all seem to have customised software packages. I know that it is cheaper and makes more sense to buy a printer and scanner but the space saving and being able to make copies without a round trip via the computer are very attractive. TIA, Jethro
