I bought an NRS frame a while back, and built it up with the parts from my old bike, and have been replacing them one at a time. I just replaced the fork(an old RS Jett) with a new Marzocchi MX Pro that I managed to get for $299. Great fork, atleast compared to that crappy old Jett. You can get the MX Comp ETA for about $269 or so, and that would be a great buy also. Thats actually the fork I would have gotten except I managed to find the Pro for only 30 bucks more, so how could I not do it. Check out the reviews on it at MTBR, they are all excelent.
