im a noob to soldering ,what should i get to solder with..a soldering pen/gun? let me know whats the best thing to get

15 watt soldering iron, thin solder (i would look up the size but i am not at home right now), and some flux for the d0 point.

60/40 rosin core solder

63/37 or 62/36/2 solder, a flux pen and a 15W soldering iron will do the trick. You should be able to get all of these at a Radio Shack or a local electronics store.

60/40 solder will work too, just the other two I mentioned above are used for high-quality, high-reliability soldering.
