Thanks for input all. I cleaned-up with all the mini-expansions on Cundco. Getting in bulk from Europe made sense, even with shipping costs, compared to the high prices charged on eBay for US resellers. I'm looking at reselling my first base set cheap on eBay and then keeping the Big Box along with all the mini-expansions. I also added Abbey and Mayor as well as Bridges, Castles, and Bazaars since those seem to keep with the spirit of the game without introducing radically new dimensions. I'll also get an Anniversary edition in May to round out the set.
