If you've got some soldering experience it should be fairly easy for you to build the board. Soldering the switches is pretty easy, just make sure not to underdo the solder. I had purchased a Redscarf numpad from another user a while ago and the solder joints were poorly done with so little solder on each of them that they were falling apart! I had to completely redo all the solder just to get its basic functions back. Just have fun with it and take your time, as long as you don't apply too much heat to the board you should be fine, in the end building is a big part of the fun.
