"I have NEVER bought an expensive blade.. are they worth it? I see them for 60 ish dollars.. compared to SIX dollars, I have a hard time believing they will last 6 times as long as that cheap blade.."
you get what you pay for.......we don't own a jointer but we have a RAS, a miter saw, a table saw, and an expensive skil saw and trim saw. the better blades will get you more mileage and smoother accurate cuts with no smoke in your shop scott, and can be resharpened, cheap blades, just throw them away, can't really be resharpened. keep in mind buy a blade for the material you are cutting with any of these tools, not something general purpose. also we don't buy cheap router bits for the router or the laminate trimmer.
buy a $60 blade once, and you won't go back to the cheap stuff. you will spend more money buying cheap blades everytime they go dull vs buying a good blade that will last much longer, and can be resharpened by those skilled who know how to do it.
just my humble opinion.......
