Nice wish list. I definitely want to get the Chewie, 3PO, R2-D2 sets together. That would be a great trio to display.
The Office looks like a fun set. The Simpsons and SpongeBob would be a couple of TV themes I'd like to get, but those sets are retired.
My white whale is the UCS Death Star 75159. But at over $1k for a new sealed in box...ouch. I'll more than likely look for a used complete set in the $700 range if/when I feel ready to pull the trigger.
