I've been tempted by one; various vendors were offering a networked Brother machine for ~ 150 quid earlier in the year. Consumable costs worked out to be about half those of my bubblejet going on manufacturer's rated page count.

I came >< this close to buying one, then my current machine remembered how to print colour properly (for a while it was swapping cyan and magenta, which was very confusing) so I didn't. Still tempted, though.
