This is what I got for my £50.
The power supply came with a 2-3 pin adaptor but I might rewire a new longer lead as the supplied one is very short at only 400mm.
The 24v output lead is a bit longer at 900mm. Both leads are pvc insulated.
The lead to the soldering iron itself is 1000mm of nice flexible silicon cable.
It didn't come with a manual but you can download one here.

The controls are simple
Turn the knob to adjust the temp
Press the knob in for 1 sec & the iron will enter 'boost' which heats up the iron by an extra few degrees for a set amount of time, both of which are set in the settings menu. (10-99 seconds & 10-80 deg c)
To enter settings hold the knob in for 3 secs.
The settings are fairly straightforward but I'll explain some useful ones.
If the iron handle isn't moved it switches off, but if you lift it again it comes on again & it heats up very quickly. If you don't use it for a longer period the whole unit shuts down. Both shut down times are adjustable from 1 to 99 min.
Battery guard - if you are running off a battery you can set this to shut down the unit before it drops the battery below a minimum voltage.
This thing is tiny!
Also bought a set of tips, every one different.
Not used it in anger yet but I'm looking forward to it. I'll need to mount it on something for protection plus make it easier for storage.
