I was replacing the Office Depot cheapo chairs every few years because something always broke, the cylinder leaked, the arms fell off, the wheels broke... my Leap is built like a freaking tank, and I've had it for 2.5 years now (I think) and it looks no worse than the day I unpacked it. No rattles, no fasteners loosening, nothing.
My Leap looked brand new, no scuffs on any of the surfaces, and the wheels looked barely used. The Aeron looked "used" but still in excellent condition, I'd say maybe 85-90% of new.
Craigslist can also be a good source if you live near a big city, but as with everything CL, caveat emptor.
