Interesting little 'quiz'.
I chose the expensive chain in 4 cases, but it was marginal in very case, and it seems that its mainly because I like the 121 on this source sound more than the 57 (chose it 4 times, and that to me isnt a 'more expensive mic is better' thing, its a 'thats the tool that fit that job' thing).
Anyway, its a fair point well made. I wont say that 'you dont have to spend loads for a good sound' as I dont think any of these are actually a good sound, but it is, imo, fair to say that first, what you get for your money does not scale well with price, and theres still a chance that you would actually like cheaper gear better if you didnt let price tags do your thinking for you.
I buy gear so people can look at my gear list.
