I know this is very late, but I forgot to mention these. Its about R250 above of your range but these I like the most.
A nice one for fine work, but keep the tip clean and tinted at all times, my kids used it to melt holes in Plastic for a school project and i ended up cleaning it for weeks before it worked fine again. A rebranded version is available from Micro Robotics.
And this is my absolute favourite, even for soldering the D1 Minis, The picture below shows the result of one I have done in less than 2 minutes, heating time included. It draws about 150 watts although its rated at 100Watts. I am by no means a pro in soldering, but enjoy this Weller a lot. (My very first soldering iron in primary school was the same type, and if my memory serves me well it was a Weller as well)
This is how fine that tip can solder:
And just for interest sake, my favourite soldering fluid/flux is MTS Crystaline Soldering Fluid, available from most hardware stores at R75 for 500ml
