I would suggest to not buy old X-tool. It sucks for working for prolonged time. Handle simply heats up really fast and becomes impossible to handle. Also you need to buy replacement containers for solder. But the worst part there is also a small filter after container which gets wet from flux fumes really fast and suction force drops tremendously. It's OK for occasional component removal. But if you need to deslolder a lot of pins, like x16 PCI-E connector, it becomes a real problem.
