Shameless plug here but I'd say Common Node is pretty good: https://github.com/olegp/common-node - it lets you write your server using a synchronous style while retaining the low memory usage and quick start up speed of Node.js.
For example https://starthq.com is using about 35MB of RAM and is easy to debug despite some pretty complex business logic around generating site thumbnails.
