I don't care about fashion either. We've just had bookcases built in - the full length of a wall and into an alcove, so a lot of wood. We used walnut, which is dark, but we love it, and we're the ones who are living with it. I'm not planning on selling (or giving them away) any time soon, so I don't care if it's fashionable or not.
If you like dados, bikergran, get them? Are you planning to sell up soon? If so, and if you think they might put off the sort of people who would be interested in your house, then maybe think again, but otherwise, I wouldn't let fashion sway you.
(my sister was telling me that those Hilda Ogden ducks are very desirable now, so what goes around comes around anyway
