Waste money? No! Spend it responsibly yes! It is very difficult to know the real story on a used blower. The tolerances are so critical and bearings the same. How are you inspecting these exactly? I've been over this time and time again. I think the advice that you give to pickupsome used blower for 1000$ is potentially wasting someone's hard earned money.in other words you dont like doing proper inspections. you would rather waste money on all new parts. thats fine for you, but not everyone can afford to always buy new parts, so they put the time into inspection and replacing parts that need replacing.
