Andre, there are also a lot of video guides to doing SMD soldering on YouTube that show various tricks for doing it with home-grade equipment. There are even some rather heroically brave demonstrations of doing it with a complete crap 5W iron that I would not attempt myself, where the guy wipes hot solder across all the pins on one side of a 48 pin package at once with a big blob then magically soaks it up with braid leaving a beautifully mounted device. ...but there are some actually good guides that are worth watching. Another thing that can help a lot is a stereo microscope on an arm. You can sometimes find these on eBay fairly cheap. I used an illuminated magnifying loop to solder wires onto the flash roms on my PS3 motherboard a couple years ago and it was headache inducing compared to using the microscope, so I recommend steering away from the graphic designer magnifying lamps.
