Picked up my M55 cast insert from pelletdude (thanks again Steve). Going to home depot on Saturday for my first 2 tons with 2 more of oakies to follow from somewhere. Just want to say thanks to the site for all the great info, been lurking here since last year before I picked up my PE super, which I am replacing with the M55. Not sure when the install will be done yet, still have to get the PE out and sold but I look forward to the simplicity of the pellets. Thanks again for having a great board.
