When it comes to soldering especially at the component level you get what you pay for in terms of irons. The adjustable irons are useful but doesn't mean they are good quality. In my opinion good tips are far more important especially with the small SMD components. Most of the Wellers from Frys or Digi Key can do the job, just be sure replacement tips are available. There are a few models with tips that are difficult to find. If your doing a massive amount of surface mount parts you should look in to using solder paste and a heat gun/oven (don't use your oven in the kitchen, once you use a oven for soldering you should never use it for food again).
