I've been there three times while driving through Denver on trips. It's worth carving out a little time to stop by. Maybe you could plan a vacation with a variety experiences in the area, such as visiting the Denver Mint, Pikes Peak, Mt. Evans, Air Force Academy, Royal Gorge, etc.
This store is so fin massive - I guess I would have to take a two week vacation to go there and browse it - does it have a campground ^^... and I guess the flight from Austria wouldn't be the part I would have to spend on most :)
Bought from you decades ago (almost) when that location was not the address. I keep trying to direct people to you to buy online instead of say from Ebay and Amazon listings. Hope its helping. Currently in Reno, NV Last Purchase was the Archie one where Sabrina came to town and flipped the genders for a day. Wish I could more Reverse Dale stories it seemed fun.
