Review on Efficient Soldering Rework Hand Pieces: Metcal MX 5210 by Nigel Cohen

I use one (this model) for work. I personally don't own it. However, I would love to own one of these as these things are amazing. They're expensive, but they heat up in seconds, the tips can be changed quickly (like you change the temperature. There's no dial), and the thing will last for years. I've been using it at work for almost 4 years and it's great. I've honestly been putting personal projects to work because the soldering iron I have at home falls far short of these HF soldering irons. Can't wait to move to a new place in May and buy one of these.
