From Scott Guthrie's post Red Gate software (whose tools have got me out of trouble in the past) have released a free download of SQL Prompt.
This is a powerful auto complete tool for anyone developing in SQL Server 2000 or 2005. It works very well and gives Query Analyser a MASSIVE leap in power.
This should be a must for anyone who does any work in SQL Server.
Get it here but it is only available till September so dont delay.
