I second this.
You know how in the optics field where the veterans always say "don't buy cheap--make the investment in higher end now and you'll thank me in the future"? You can go further up the pricing tier if you delve into used. A Herman Miller Aeron chair is seriously expensive brand new ($1,099 retail, but often discounted). But if you're near a major city, you can often find used examples for a lot less. Of course, condition is key. I picked up an Aeron chair for $200 off Craigslist. It had a busted left armrest. Well, I was able to replace it (found a workable used part) and the chair works great. This was 22 years ago. It's still my office chair. Excellent support!
