I am lucky enough to say we are mid build on several sets right now.
I just snagged the Dutch version of the old 725 and 741 train set, and we are currently working on Rivendell with the light my bricks kit, as well as the old Scooby Doo 75903 set to round out that collection!
I took a big hiatus from building due to work and other commitments but am exited to be back in the thick of it.
Check out your local garage sales and community buy/sell/trade pages.
Some of our best finds (and big totes of random bulk legos!) have been found just by pure luck.
