I don't know of anything good for under $300.

I would recommend looking at the Discovery Back family of OfficeMaster task chairs: http://officemaster.com/products/index.php?view=family&p...

I especially recommend one with the "DCS" feature (extra memory foam.) I have had an OM chair for a year now (from a different family; the "Yes" line), and the seat foam is still as cushiony as when it was new. Beats my old Aeron hands down. I miss the scapular impedance feature that is in the Discovery Back line, though.

P.S.: whatever you choose, be careful. Mesh chairs are nice for light/medium duty use, but they're just too hard for extended duty use. That's my experience, anyways.
