Not all soldering irons are created equal. I went into this venture with an old Weller SP23 hobby iron. I thought I had a decent iron for this stuff. I struggled a bit with tips and heat, but wrote it off as inexperience. Then it was suggested to pick up a better iron. It was suggested that a CSI unit would be much better. I bought one, and after the first use, I wish I had bought it when I started. There are better ones than this one, but it is really hard to beat the price for what you get.
When purchasing be sure to get extra tips, as it only comes with one.

Either of these units are great...
