After spending a bit too much time on OzBargain I came to understand this chair is a fan favourite.
The TL:DR is it's definitely no Herman Miller but it's also a fraction of the price. There doesn't seem like there are better options for the same coin. I have one and haven't had any issues or desire to change it, so just ordered a second for my two kids. My wife bought chairs for us both at x2.5 the cost from a reputable brand, they're great but I can barely tell the difference between those and the ErgoDuke.
Currently $189 or $179 after using the coupon EOFY10. It'd be a real bargain if it was free shipping (which it is to some area's) but I got stung $69 to get it to WA.
Price in title please..
