I can attest to the quality of FD Puzzle blade. They made all the difference in the world for me. I use them for things that aren't puzzles. One word of caution--they are a very aggressive blade compared to hardware store selections.
Just slow down the saw a little 'til you get used to the action. You should see what they do to the edges of oak--looks like it's been burnished.
And Mike is a good source for the blades and a great guy to talk too. He really appreciates successful stories. My "Homesick Sawing" post in Works in progress was done with FD puzzle blades. (Only two--I got a little tight on the tension with the first one)
