My venerable Lexmark packed in a while ago, and being a total cheapskate, I went out and bought a Canon S200 from PC World for £60. The printout is not fast but it is very respectable. Black ink cartidges very cheap (£7), colour cartidges less so (£25). The printer can take a colour cartidge and a black cartidge at once, so there is no cartidge swapping required.
My advice would be that unless you need a particular feature e.g. very fast printing or photographic capability; a cheap printer will be bertter for you than a dearer one.
