If you're in the US, I've had good luck buying Aeron chairs used on craigslist (in the $200-$250 range). I would also say check FaceBook marketplace (I've found some good things there - though not chairs). Finally, as someone else also mentioned, I have the ErgoChair 2 ( https://www.autonomous.ai/office-chairs/ergonomic-chair ). I don't care about color, so I bought the green one which was $20 cheaper.
