re: Saw Blades-lets talk, the good and the bad ?

I've had the same 40 tooth Marples combo saw blade on my cheapo Delta 36-726 table saw for about 6 year I think.  Only time I took it off was when I used a dado stack.   I have done everything with it including resawing hardwoods and it has never let me down.  It still gives me glue ready edges.  I have no doubt that a good rip blade would work better for long rip cuts but I hate changing blades and this one just seems to work.
