A new kitchen or not?

We remodelled our kitchen shortly after we moved into our house. It's a little over twenty years ago, and some parts of it are getting a little worn out. We could just have it repainted - or we could have a new one built for us. The problem is, I don't like to get rid of stuff that's still working fine, but on the other hand maybe it would be nice to change the colour to something else than blue. But, as the kitchen cabinets are also blue on the inside, we cannot paint the whole thing in a different colour, as that would be too much of a task. Well, well ... I don't have to decide just yet ...
