Chainsaw Repair

Maybe I'm not understanding correctly, but if you already have a 40, 50 and 65cc saws, why would you want to spend money on another 45 or 50cc saw? It would seem to me that you already have the midrange pretty well covered. Since you do not state make/model of the saws you have; my only advice would be perhaps you should consider a 'professional' saw like a 543 or 550.
