Lenox just came out with a new blade for resawing... mine is on the way. I will post a review when I get it. It has a thinner kerf (less waste, less sawdust to remove), and a new body metal (may work on smaller saws), and if I remember right, is down to 1 or 2 carbide teeth per inch. I was a big fan of the TriMaster, but Lenox doesn't recommend it for wood any more... the new blade was specifically designed for wood instead of metal, and will cost 50-60% as much as the TriMaster (now that is a new feature I really like).
I have heard really good things about the woodslicer from Highland Hardware. It is a very thin blade, which helps it do well on resawing, and makes it require less tension (same psi, but with fewer square inches in the blade cross section, fewer pounds tension, thus easier on smaller saws.) I hear that, with the thinner teeth, it doesn't last as long as some of the other blades.
