In my opinion they're nuts because no matter how a guitar looks or it's specs there's zero guarantee that it's going to sound spectacular. Odds are as well that the best sounding guitars aren't the best looking ones if rock and roll history tells anything! I think the best strategy when hunting for a guitar is to have a general idea in mind and play tons and tons of guitars until you find something very special that fits you. In my experience I've probably played over a million dollars worth in guitars in the past 12 years and only found perhaps 3 or 4 of those to be extra special (of which I own one). Maybe the goal isn't to find a magical guitar for some, rather they're looking for something beautiful to look at? maybe they haven't figured out the tried and true formula for finding a substancial ax, or they like the possibly never ending journey towards finding the one?
