I have a Weller PU81 base + WSP80 and I'm quite dissapointed in it.
It is a reasonably quality product, but it is too expensive compared to the quality.
It has a redicilous "stop and go" stand. If you put it in it's stand it cools down to room temperature and you have to wait 20s after you pick it up before you can start soldering
That was a big dissapointment (And got disassembled in the first week).
Also, the tips do not connect well to the iron. They have a fairly small round contact surface, which is adequate, but there is a stainless steel sleeve over the whole assembly, and that gets worked loose by the repetitivy expansion / contraction of heating and cooling.
This would have been acceptable for a EUR 100 Iron, but not for the almost EUR 400 I paid for it.
This would at least have needed some kind of spring assembly in it to keep it tight.
Dit you see the recent EEVblog about the Weller Iron that did not have a fuse in front of it's transformer?
Kind of redicilous if you ask me.
There are some very good Irons out there JBC seems to be top notch, but you also pay for that.
For around EUR 50 to EUR 100 you can choose from a multitude of fairly well built temperature controlled soldering irons from Ali / Ebay / China / etc, (Including some spart tips) and If I didn't have my Weller I would buy one or 2 of those. I like the TC100, but unfortunately the models of the tips are rather limited and they're also quite long.
Having 2 separate irons is very handy when working with SMD resistors and capacitors, because you can then heat both sides for rework.
This works just as good or better than the soldering "tweezers" and is a lot cheaper.
