Hmmm. Soldering on some header pins isn't really that hard. Assuming you have previous experience, and a fine tipped soldering iron, it doesn't take more than 10-15 minutes of work. I haven't soldered for a long time and was able to do so without issue. The solder joints were good too, shiny and conical as they should be. Just need to take it slow and be sure to keep your tip clean.
