Maven 2 repositories

My company had to choose a good maven 2 repository and I was blinded by the number of choices available and features to choose. After reading through the guide here:http://blogs.exist.com/oching/2007/11/05/the-hype-about-repository-managers/
I decided for archiva.

For me the single most compelling point was 'purging'. We have had loads of issues in the past with disk sapce and that was the point I needed!
