So what's a good soldering iron for a hobbist? Is the TS-100 that was much hyped on the internet some time ago a good choice? Or the TS-80 one? Or should one go for more traditional irons?
I've heard good things about the TS-100 as well but I've never tried one so I can't confirm anything about it.
I solder so infrequently that it felt like spending $100 on an iron was overkill, and I couldn't have been more wrong.
My only regret is not getting the analog version because Hakko kinda sucks at making digital interfaces.
If you want some good primary iron, buy a Weller or a Hakko. They are widely available and have a good value/price ratio. Weller WS81 or Hakko FX-888D are both great starter irons. Most likely serve you for life if you don't need it to do any specialized thing.
(I personally have a Metcal PS900, very happy with it)
