Honestly, I would save up for a thermocouple-controlled soldering iron. I personally use a WESD51 which I know for sure is out of your price range, but for you, I like the look of this guy.

I've been using my Aoyue 936 for a few years now. Heats up quickly, and uses Hakko tips.

Fairly light usage, but it's worked well for me, and hard to beat for $36.
