Soldapullt original vs III

I use a Hakko 472D-01, and it works beautifully. I've desoldered thousands of connections with it, and have never had any damage to PCBs or components. I have two different size tips for it, and haven't had any issue with the tip tinning. Once the solder melts and you hit the button, it extracts the solder far faster than it can cool, so I've never had any problem with cooling the joint to quickly. Patience is also required. Patience is almost always a good idea, but it's not required with a good vacuum desoldering station. Last fall I installed a DIN 41612 connector on the wrong side of a board, and only discovered that after soldering more than half of the 96 pins. I thought it was going to be a nightmare removing it, but the Hakko made short work of it (less than 5 minutes), and it came out very cleanly. Hakko says that the replacement for the discontinued 472D-01 (110W) is the FR410-03 (140W), and it looks like a nice unit, but it is much more expensive. The FM-204 (70W) would be easier on the budget, but I haven't tried it, so I have no idea whether the reduced wattage would be an issue. Some people may be unaware that with temperature-controlled soldering equipment, more wattage is almost always better. That is NOT true for uncontrolled (or poorly controlled) soldering equipment, such as cheap soldering pencils; with those it's quite possible and easy to damage boards, as a consequence of either too little or too much wattage.
