This depending on what Project you will work..For me weller is top class or also hakko. Soldering stations or Soldering iron with adjustable temperature is good for making more projects. You can see this from Hakko https://www.hakkousa.com/products/soldering/hakko-fx-888d-digital-soldering-station-10143.html
or if you need a good soldering iron for good price you can see this Soldering iron kit form Sywon http://fanyit.com/review/electric-soldering-iron-kit-with-adjustable-temperature/ i have this one and i'm satisfied
or somthing proffesional from Weller http://www.weller.de/de/Weller--Produkte--Produkt-Details.html?article_id=D0268797001454428828A279#{"string":"","current_site":"weller","current_brand":"Weller"} but the price is very very big
