For me, it was time to update to the new X-wing and TIE fighter. I also managed to find both at 20% off so was quite happy with that! On balance, I think Lego have done a pretty good job with these sets. I haven't bought new versions of these ships since their original issues way back when but I did get the most recent version of Vader's TIE Advanced, so I figured I should get the X-wing and standard TIE to go with it -- and updating my collection was long overdue...! There will always be some aspects of new sets that folks don't like but, hey, it's Lego -- so just custom mod it!
What I need to do now is get the new Y-wing and a second TIE wingman for Vader, just to complete the scene...!
The majority of my big purchases over the last year have been back-filling the gaps of stuff I wanted a while ago but either couldn't afford or didn't get around to buying at the time. With some strategic watching, I've managed to pick up 8038 The Battle of Endor and 10198 Tantive IV at really good prices from eBay! I bought a couple of the Endor battlepacks to complement 8038 too.
I've also just bought 7958 Ewok Attack to round out the Endor battle scene. I would never have paid the full asking price (insanely expensive) but finding it at half price I caved and bought it. Finally, I picked up the new Desert Skiff at the same time (again, 20% off) because I just kinda like it, especially the new Luke and updated Boba.
