Simon said that many people in Hong Kong aren't buying airsoft and WW2 stuff as frequent as before due to rising prices and decreasing (China made) quality.
It was true before my very eyes. Well, after much searching, I bought just a repro German DAK Y-straps and a pair of USMC HBT utilities uniform set from Dai Bing. This set is from Sam's Militaria of Japan and I did not mind paying HKD1050 for the quality!
More info and shops addresses to follow.
