I'm with Mike - it makes the most sense to first do what I am officially calling the Builder Kits™. And I agree that if you want a whole Sealab, you'll spend just as much money as it would cost for him to make the whole shebang.
Let's focus on our goal - making spaceships!!
I'm thinking this is the best order to attack the releases, gauging on who is building what:
Escape Pod
X-Wing
Colonial Movers
Battlestar Galactica
ANH Star Destroyer
Sandcrawler
Turbo laser
2' Death Star Tiles
Blockade Runner
Any total parts overlap will trigger a simultaneous release. Price will be determined by how many parts/how much it costs to make... no idea yet. Will post Sealab photos on Tuesday, so we can continue to ID... but we seem to have enough on some of these to get started soon!
