Rockler carries these blades but I would think hte variety will be determined by demand, like anything else. I would also recommend buying a utility blade, fro wood what may have metal or other things that sound damage your good blade. I use an Oldham but a basic Freud is a good choice, too. If you fo to any of the woodworking forums like the one DaveHo and I linked to and see someone whose screen name is CharlesM, he works for Freud (at least on the
www.taunton.com forum). At that forum, you can look at older threads about saw blades and see various comments and arguments about which is best, etc.
You're looking at the 10" along the side, or for a smaller blade? I have seen the 10" for not too much more than the 7-1/4", though. If you can wait a bit, go to the Woodworking Show and see what they have. They always have a guy cutting wood to demo it and if you'd expect to see rough edges and tooth marks, you'll be disappointed. The surface is so smooth it's shiny.
