On the roof cost compared to island thing ...I think the cabinet industry has worked against itself. In some cases they even have statistics that say you will need at least two kitchens before you need another roof. Instead of letting magazines and
television dictate styles ,such as "white","dark",why not true custom designs appropriate to the house? Islands are just a current style that will run their course and then be laughably passé. And some people who can't afford an island might buy
an enduring table.
