True you can find a NJS frame used for under $600 from time to time but there is one thing to keep in mind... it was CRASHED. Maybe there is nothing wrong... and maybe there is. Not saying I would buy either the Kazane or the NJS frame (i'm just not into lugged steel) because of that fact but it should be taken into consideration. Compared to any NEW steel track frame for around $600 it's a pretty damn good deal.
