I was in your position about a year ago. After doing my research, I decided to BrickLink CC, MS, & GG. I’m very happy with the outcomes (See attached photos). I did make some judicious substitutions an astute observer will notice but I’d say they’re 95% accurate to the original designs. I then took them a step further and made custom interiors for each. For Grand Emporium, Town Hall and Fire Brigade, I got mostly complete copies from eBay - From my experience, it pays to be patient and buy something that looks like it’s in good (complete) condition but be prepared to complete a few odds and ends from BrickLink once you tear down and inventory the sets. If you’re interested in going this route, I can chime in with more observations from my experience. Good luck! Sent from my iPhone using Tapatalk
