Starting a new 40k army - Start Collecting!

With the release of the new 'Start Collecting! (Insert Chosen Army)' boxed sets by Games Workshop I have decided to start on a new project, namely, the Tau Empire.

Before I talk about the new army I will be building I really need to point out how good value these boxed sets are and this post will be deidicated to that. If we're to look at just the ones for 40k, the factions currently included in the 'Start Collecting!' range are the; Astra Militarum, Skitarii, Tyranids, Necrons, Space Marines, and, of course, the Tau Empire.
