The 926 ran from late 1980s? to 1999, when the 936 took over until 2009. Its very much the same electrically and uses similar handpieces. They are easy to troubleshoot as they have no dedicated firmware.
A main drawback was by integrating the station and holder it caused a lot of cosmetic damage to the station as folks tended to hit the station with the hot iron, as well as burn the cord.
The model pictured does look a lot for wear for $60, you can get a new FX600, which is a whole 936 in a handle for $45, new, ~$50 delivered via AdaFruit.
In 1990 a new FX926 cost about $55.
