I haven't played 40k since 3rd edition, and like you, decided to jump back in with 9th. Those starter sets are just too hard to resist! I got myself the Command starter, but it will take me a while to put it all together, as I have a lot of other projects on the go. I've also watched a couple of 9th edition battle reports by Guerilla Miniature Games to get a feel for how the new edition plays, and - hoo boy - it's completely different to 3rd edition! Gonna take me a while to get my head around how the game works now.
