Muddling our way through a kitchen remodel. We started out using the ikea tool at the suggestion of several people and found it so frustrating I gave up and bought some graph paper and have been "playing paper house," but it would be so helpful to be able to see some 3D mockups.

I think the obvious answer is "make an appointment with a kitchen designer"- all in good time!- but outside of that option is there a [good, free, easy to use, online] tool I can use to play around with?
