Sound like MS046 is not that much better even thou it's a 76cc saw vs 72cc MS462. I was think the 4 extra cc would be difference. The AV in last 20 years has change and I do think Husqvarna has the best at this point. A used saw with No warranty is always a gamble if you can't look inside the cylinder. With a possible 25-year-old saw (not sure the year of this saw), I'd change the rubber and seals. I'm going to advice going with a new saw I think it's too much money as well. The MS462's are good saws. With 500I at >$1600, the small chip guard and air filter issue...the 462 seems like a better deal. The weight and power of the 500i is attractive. I don't own one nor have I ran one but as I get older the benefits the 500I brings is attractive.
