I think its more popular now because of the increase in popularity of track bikes. I personally like them because they are quality parts, sure not the lightest of most high tech, but I don't need them to be. I also dig how they look and I'm a believer in japanese craftsmanship, not to say american customs aren't as good.

I wouldn't pay much more for NJS parts over other quality parts or really go out of my way to get them. I'm just as into italian frames and if I ever find a Schwinn track frame in my size I'd pay more than what its worth for it.

I don't think it's so much the NJS stamp for me, it's more the styl, look, and ride of the lugged frames... and the puurty sparkly paint.
