I don't buy that kind of bargain anymore. Almost never have good results for long term use. And if I'm cutting some expensive stock, I want good blades in a carefully set up saw. For ripping, I am very fond of the Freud glueline blade. But I also have a full kerf Freud blade for general use and crosscuts. The risk of flying teeth just isn't worth it to me. And you know that the little bit of carbide on the tips is the lowest quality they can find. A really good blade can be resharpened 2--4 times.
Using a cheapie blade for construction use makes sense to some, but construction grade lumber gets dumped in bulk at a job site and and begins collecting who knows what. Sounds like a setup for an on-the-job injury.
That's how I see it anyway.
The more I do, the less I accomplish.
