I would also roll my own. I've tried several generators and there is always something that doesn't quite work how I want it to and the documentation is often bad and outdated.

When you roll your own not only is it way simpler than existing solutions it won't change from under you. I blog very infrequently and often from different machines or operating systems, the last generator I used had completely changed between posts and I either had to relearn how it worked or make my own.
