The TS100 is good, particularly with third party firmware from
https://github.com/Ralim/ts100However there are 3 flaws I think...
1. Getting a grounded tip is difficult and clunky - you have to hook up a separate earthing wire to a screw near the top of the handle, above the display.
2. The iron itself is made of plastic and the build quality is not that great.
3. The tips are expensive compared to similar Chinese T12 / T15 tips. TS100 tips are approx $9, Chinese T12 tips can be had for $3.
I have often wondered if the Chinese Ksger / Quicko STM32 stations are a better choice. There are some which come with a built in power supply, a grounded iron tip and you can buy a metal (Al alloy / stainless steel) soldering iron (pencil) to use with them if the default plastic one is no good. Also, you can use Chinese T12 tips or even genuine Hakko ones with them.
However the TS100 is also a good choice and if you have already bought it, I would not sweat it at all.
