i m using a 40 w soldering iron but have problem with it
so i m searching for a very good digital temperature controlled soldering station under  3500

Soldron Micro soldering station works wonder(using it for 3 years and works awesome love it!) and its under 1000 rs...but it doesn't have a digital display(seldomly you'll need one!!)...knob style
