I agree with Audioguru, I have several solder stations from five different manufacturers, ranging in price from well over a $1000 to $150. They each have their specific function and niche, however for today to today soldering, my Weller EC2001 is still going strong after 30+ years of continuous service. I've only had to change the tip once in that period of time, there are some things in this world where it truly does pay to buy quality, soldering irons/stations is one of them.
Most professional conventional soldering station with normal sized tips for average PCB work are in the 60W to 80W range, if memory serves me. It's not a question of how hot, but how fast the iron can reach a specified temperature and the stability of maintaining that specified temperature.
It would certainly be advantageous to purchase a soldering station with a reliable temperature control system, many of the lower priced pencil and station irons have a bad tendency to rise above normal levels when not in continuous use or they simply do not have the wattage and control to compensate when soldering large joints, terminals or pad areas.
