Here is a simple alternative if you need just a monitoring tool for queries:
http://expressprofiler.codeplex.com/
I hope it won't disappear soon.
I'm currently using it with SQL Server Express 2012 to monitor queries form my NHibernate applications (didn't want to add log4net just for this purpose and show_sql outputs only to console window which I don't have in my WCF service).
Really nice and stable utility. I find it much easier to use than MS SQL Profiler which needs various settings, trace profiles for various server versions and what not. Express Profiler - just launch, hit Run, and all the T-SQL and sp_execute queries are displayed.
It's open source, you can add even more features if you wish. I guess, Clear button would be useful because now you have to Stop and Run again to clear the list.
