Ok - so I knew this was gonna happen - kinda got the Lego bug now, here's what I've picked up over the past few days....
Battle for Geonosis
Mandalorian Battle Pack
Bounty Hunter Assault Gunship
T-6 Jedi Shuttle
Elite Clone Trooper & Commando Droid Battle Pack
Endor Rebel Trooper & Imperial Trooper Battle Pack
Anakin's Jedi Interceptor
I've also got my eye on the Z-95 Headhunter and I have some Toys R Us rewards bucks that expire this coming Friday - tomorrow I'll hit up Toys R Us and probably spend them on the Palpatine's Arrest set if it's on-sale in the store like it is online.
I'm not going to go back any further than 2011 sets - and even then, I'm only going to pick up 2011/2012 sets at or below MSRP - I have no interest in going to the secondary market for these where they have the tendency to really climb in value. So for now, I'm mainly focusing on getting "caught up" for those years as best I can and then over this year I'll acquire a good number of the 2013 sets. My local WalMart has four or five of the 2011 Millennium Falcon sets on the shelf - I'll probably pull the trigger on that set at some point soon before they disappear.
