Herman Miller Embody. Had an Aeron before and loved it, move countries and left it behind.
The Embody beats the Aeron for my preference – the "pixels" aren't a gimmick, and it was more adjustable to my needs.
Pro tip: Lookup the corporate dealers/authorized resellers and give them a call. It's not uncommon to get one new for 30-50% off the retail price. You may even be able to find people who're making group purchases on some local forums.
