I have traditionally taken cheap tools, just for the price, and sometimes ok. Sometimes not. I have some old Radio Shack soldering irons that worked for most jobs but didn't this time. I needed to have my car's instrument cluster repaired and didn't want to risk damaging it and costing more than necessary. I have known Weller irons since school, university and industry. They consistently meet specs and this hardware did not disappoint. A couple of key features I needed were the ability to maintain a constant temperature and the ability to adjust the nozzle size to suit the task at hand. The hardware worked perfectly. The only thing that could have improved this iron would be to include a few basic sizes in the original packaging. Anyway, I had to buy a smaller tip separately. So you might be wondering if you need to buy the same expensive iron when there are a few more for the same price as teenagers. Even Weller has a red series that's about half the price of the blue series. I have often found that having the right tool affects the quality of my work as much as the level of my skills. Of course, if you're just learning how to solder and not risking ruining something expensive like an instrument cluster, etc., probably not. I've used cheaper Radio Shack irons for years with decent results. However, I definitely felt like I had more control over the solder joint than my other iron. A stray solder jumper to another component would ruin my PCB and cost many times more than Weller's iron. Sometimes it's worth it. UPDATE APRIL 2017 I was trying to do some repair work on a TV recently and found the 35 watt weller was having trouble melting the new ROHS solder. I have an ST 7 tip and had to add about 60-40 solder to melt the other materials. A little harsh but it worked.
