I have ordered my FT6, and have had great luck with PEI and a borosilicate plate on my FT5.
I figure that the plate for the FT6 needs to be 28.25" x 13.75". Has anyone found a distributor of plate? I can get a custom plate from PowerPlus International for $149, but I have to buy a 48"x48" sheet of PEI from McMaster Carr or Grainger for a large sum. Wondering if anyone has some vendors they like.
