Yeah. The NJS stamp of approval is to ensure that all the Keirin bikes are essentially equivalent, to level the playing field. NJS approval does not mean higher quality than non-NJS stuff. Some NJS stuff, such as Dura-ace cogs and Sugino 75 cranks are good parts and reasonably priced in comparison to non-njs parts. But quite frankly, a lot of non-NJS stuff is a lot better than NJS stuff, sometimes at a fraction of the cost. NJS approved components are intended for use by professional cyclists who make a living off of people gambling billions of Yen every year. A lot of money is involved and thats why you pay out the nose for the stuff. NJS parts were never meant to be marketed to dirtbag starving messengers and students. The fact that its trendy only makes it even more expensive. If you aren't making your living riding on NJS parts, then you are wasting your money on those NJS parts. Go NJS if you are so into the idea of NJS that you are willing to pay for it, but if you really want the best track bike money can buy or even a practical street fixie, NJS is not the way to go.
