Hi Brian- I have a '2000 Giant NRS XTC1 (purchased new in 8/00). It's a great bike, very reliable and an unbeatable best buy in 2000 (discs, SIDs, etc). Still all original except for a new XT cassette and PanaRacer Tires. I can go on and on about it's best qualities, but it would be easier to talk about the few (possible negatives).
1- Rear suspension locks up when braking (makes you more sensitive to picking the best line).
2- If your 200+ pounds like me, it's almost impossible to get enough rebound control out of the rear shock (never got this completely sorted out).
That's it. The bike flies, especially downhill. Play nice with the trees.
