Trying to repair my ECU.

Any suggestions for brand of iron? Something a bit south of 2K? :)

I get by most of the time with a $50 temperature regulated iron from Marlin P Jones. For the transistor tab, I would use an old Weller transformer gun style, and modulate the trigger to keep temperature as needed.
