I don't have a specific mirror to point you to, but check Ikea. They tend to have stuff with simple clean designs, and a lot of light pine or beach wood stuff. They also tend to have 50 iterations on a theme, so you can look at a whole bunch of options and see what you like. If you go in person it's pretty easy to tell what's solid and what's chintzy. Though the store as a whole is awfully overwhelming so prepare yourself.
