Actually they tout the steel shaft as being lighter, and the specs support that. Go figure.
Also, I seriously doubt one is going to wear out the shaft on these things before the other components have become useless. These are $200-$300 machines, splurge and buy a new one every few years guys. The engine repairs and replacements are where the money is anyway. In a business that grosses $40,000 or more per trimmer in the fleet, it's hardly worth thinking about to spend maybe $100/year on trimmers in order to have reliable ones that don't eat up your time with repairs and maintenance.
