Having used the Aoyue I found that it is not nearly as nice and does not keep temperature nearly as well as a nice Hakko soldering iron. The Hakko FX-888[1] (replacement for the Hakko 936) is absolutely fantastic. I used to own a Hakko 936 until it got stolen and it was by far the best soldering station I have ever owned.
