I always get Aerons used on CL. In the Bay Area, if you shop around for a few days, you can get one for $300. My last one came from a dentist office. I sold my OK-condition size C for $280 and picked up a better-condition size B (which is actually my size, at 6'0 and 220# with a 44" chest and 36" waist) for $300 later that day. It was the second one I called about; the first person didn't call me back fast enough. Agree that the lumbar support is more comfortable but PF does have some benefits. I like that they redesigned the arms which support the seat above the part which connects to the top of the gas cylinder. Hopefully this will have less tendency over time to wobble.
