I bought the (I think) Aldi version when it appeared here a while back (no auto solder feed, but adjustable temperature).
I've done VERY little pyro so far but have used the above iron for a bit of trying out. I also bought a set of different solder tips from our local DIY place - all quite small in size but different angles/shapes mainly. All screw directly into the above iron.
I must say that some more experiment will be required before I reach definite conclusions, but so far, fiddling with the various bits and the heat setting of the iron (to mysurprise it doesn't always to be set at "flat out"), I seem to be producing quite encouraging results.
I stress that I'm talking about minor detailing here (of scroll saw Intarsia aeroplane "pictures") so I'm sure that sunnybob's dead right, this type of set up will NOT have enough power (heat - wattage) to do those big pyro pictures you see from time to time.
But within the limits described above, for "fine-line detailing" I think the above is going to work fine.
Why not try it, nothing to loose (you can always use it as a soldering iron if you get fed up)
Edit for P.S.
The above pic (posted after I started drafting my post) looks exactly like mine, but I only got 1 reel of solder with mine, and as said above, no auto solder feed. So I guess my really was from Aldi, but clearly, very little difference externally.
To add to the above comments, about the only down side I've found is that the cable connecting the iron to the power unit is somewhat stiff and inflexible, so CAN be a bit of a problem when trying to do fine work. I MAY get around to changing the cable on mine, that stiffness is a bit of a nuisance. We'll see.
