Alternative to DirBuster - dirscanz.py

Often when testing, I need to run an automated scan for common directories on a web site. The traditionally recommended tool for brute forcing directories is DirBuster. Unfortunately along with occasionally crashing, it also kept filling the results with irritating 500 error files and other bad results requiring manually sifting.
After getting annoyed once too often with DirBuster, I went ahead and built one that was tailored to my own needs. It has the following useful features:
- selecting file types to search for
- HTTP return codes to ignore
- Depth to search to
- All the usual functions

The python source can be grabbed here and an example list of directories and files to try can be downloaded here. Hopefully it will provide a few of you with a much needed alternative.
