+1 for Leap V2 from me as well, I've had it for a few years now and I only have good things to say about it. I actually bought the Herman Miller Aeron first, but didn't find it very comfortable because of the hard plastic frame around the mesh seat, so I ended up returning it. The only thing I miss a bit is how the Aeron offered back support when you lean forward, which the Leap doesn't do. For me the Leap is less of a gamble, it's much closer to a regular office chair than the Aeron, but still worth the price, it just makes other chairs feel flimsy and still looks brand new after the years I've had it.
