DASL client

Sorry to post in the WEBDAV v. DASL group but there is more activity, less
spam here.
We are building a WEBDAV front-end to our ERM repository and supporting both
browse and search functionality. We can use a plethora of clients for
testing the browse portion; IE, explorer DAV-Explorer, etc. We have not
found a good DASL client (or a bad one for that matter). Does anyone know
of a good, free or pay per view, DASL client? We would prefer to
concentrate on our server rather than write a DASL search client.
Thank you all in advance,
Steve
