Hi Sebastien, I used 137ESD for a short time, and I can tell that the product you get is worth 99USD , because you see the exact temperature on the tip and the temperature you have set, with help of a switch, and i think it has a stable temperature within 1-2 degrees error band. That is needed for temperature control. If the control circuit is not digital and contains no measurement, then the thermostat is mechanic or at least a wide temperature band & hysteresis one. Also the ceramic heater heats and cools fast, i can say.
The stand and general material quality is also good. The kind of device for 99USD is the best you can get for that price if you won't pay more hundreds and get a more professional and complicated hot air SMD (de)soldering station. The tip alternatives are also avaliable for 137 ESD. If you can afford it, i can say you can use it a long time with tip changes and buying tips which you can need in time. But if you want a cheaper one, of course the $20 one is not bad. It has also a stand and tip simple temperature control, i assume. Of course, all are my thoughts, and there is not only one right choice on this matter.
