I'm using a $50 FINGAL from Ikea, same place I bought my desk.
It was comfy for a few months but now I have to use a thin patio pillow to keep it comfy. The back part is fine and I like how low the arm rests are, but after watching a LinusTechTips vid about a Maxnomic Dominator and seeing all the bonus features and build quality, I kinda want to look into what else is available.
And of course, the first place I go to is the Computer sub-forum.
So what are you guys using? Did you pay hundreds for a super fancy chair or are you rocking some milk crates? Any suggestions for someone who would be willing to spend $200 CAD on a new chair?
