Well the first question is: How much are you willing to spend on a soldering iron/station?
For less than $20, I would probably recommend the Hakko 936 clone on HobbyKing (wait for a few minutes, the price will be lower).
For about $50, I would recommend a slightly better digital Hakko clone. I don't really have any names, try searching it up on eBay. Otherwise, a second hand soldering station would be your best bet.
For about $100, the Hakko 888D/Weller WES51D would be your best bet. Be wary of Hakko 888 clones! There are a lot of them!
For over $100, that's probably the station we all dream of
Metcal and JBC would be your best bet.
Another way is to make your own soldering iron controller (there's a lot of guides on the internet), but of course you'll need a soldering iron to make it.
Another forum, the EEVBlog, has a lot of posts on this subject, so this might be helpful in your research.
Hope this helps!
