I have a local shop that sharpens and makes blades for band mills, there are a lot of saw mills around here. He keeps rolls of 3/4 and 1 inch and makes up blades for me and it is much cheaper. He can even sharpen them. There may be a shop near you.
I have a MM20 and typically go with Lenox blades through Specrtrum Supply online. The Trimaster or Woodmaster CT for your resaw blades, and the Diemaster 2 for other needs. Although, the Diemaster makes for a good economical resaw blade as well.
