I have a handful of automotive wiring jobs I need to take care of and figured I should probably solder some of the connections. I’ve used them a few times over the years but I don’t own one and don’t really know much about them. I did a quick Google to check prices and am finding a pretty big range. I see a $5 one at Walmart and others that are $100+. So what should I look for in a soldering iron? I was thinking of spending in the $25 or less range.

Here is a dog because soldering iron pictures are kind of boring.
