Huagati DBML Tools for Linq-to-SQL

I haven't had a chance to use them yet, but the Huagati DBML/EDMX tools look interesting - a set of extensions to the DBML designer in Visual Studio 2008 that provide some additional functionality, including the much-needed ability to update your DBML to reflect changes in your database schema. It's a commercial package costing $119.95 per user, but a free trial license is available.

With Microsoft effectively abandoning Linq-to-SQL, it's good to see tools like this in the wild. Of course, it'd be really good to see Microsoft open-source Linq-to-SQL and let the community develop it as they see fit... but failing that, these tools can make things easier if you're maintaining an existing Linq-to-SQL system.
