the expensive ones were reviewed out of Business 2.0 mag. most of these have wheels that are dual thin plastic things, so don't expect it to do well on carpet.
Herman Miller Celle, available at herman miller $564-984
the one with the mesh plastic back and seat cusions have just enough give. the open back also lets air circulate, leaving you cool (hope your office isn't too cool already). the knob in back is hard to reach. maybe too much plastic for the price. comfortable.
