Thanks for all the support, it is appreciated. Have been able to source Die Pest fairly reasonably with a few other gap minis (Die Windrosen II; Der Graf; Kathedralen Deutschland etc.) I didn't previously own. I'm blown away by all the offers of help as well as the impressive completionist collections I've seen from all your profiles. I've tried to respond back to all of you in the community who posted here or PMd me. Ended up taking up Mr Meeple on his offer as all the purchases I made ended up being in Germany with mostly nation-only conditions of shipment. For Die Pest I think I paid about 20€, which was excellent given the last month they've all fetched at least double and triple that. I also felt justified monetarily in that Der Fluss II and III cost me about the same. However, I think Die Belagerers and/or Die Katharer are a little beyond me at the moment and would degrade my sanity had I paid 80€ for six (6) tiles. I just can't quite reason with its state of rarity, yet I respect the market nonetheless.
Hopefully some benevolent knight will offer up his/her Carcassonne estate some day! Anyway, thanks for helping me get closer to that illusory 100% Carcassonne collection.
