Well, I never bought an expensive niche frag, but I have swapped for a lot of samples. Some I like, some are interesting but not really wearable, and others are incredible (meaning I can't understand the thought process behind them; an example is Bois Farine). But even those I like, such as Costume National 21, just seem to sit there and become boring or nauseating after a while (or have terrible longevity, like Safran Troublant). Of course, some have notes I just don't want to deal with. I'm glad I found BN, especially for the reviews and discussion of the "cheapos." If there was just one expensive niche frag that got all the attention, I might have blind bought it. Thankfully, there were so many that I decided to focus mostly on the cheapos (and any niche samples I could get in swaps). I still have trouble believing how good so many cheapos are, especially in terms of wearability.
