Temperature Controller for my soldering iron

Soldering Iron Temperature Controller

After buying a crap soldering iron, I found that its not good enough to solder even the most basic of things. I have a $30 gift coupon in RobotShop thanks to jorgen and I thought of using it to buy a new iron for me. Ideally, I want to buy something like this but my budget is limited, so limited that I can't buy it.
