Step 1: So you want to Solder?
New Cold Heat soldering iron for Easter 2 years ago. Sadly, within the first 5 minutes of use, the thing burnt its tip off and i never bought a new one. I would strongly advise anybody against getting one of these due to the fact tips cost little less than a new ColdHeat. These are little more than glorified LED flashlights.
If you decide on portability, Weller makes a butane powered one. I have never used a butane iron, but i would imagine that it would have to be better than a Cold Heat.
UPDATE: Today i decided to give the ColdHeat one more go (even in its already dehabilitated state) and one entire half of the tip broke off this time. Picture below.
