i use 3M 348D 80 grit psa sanding discs. ordered them from rs hughes online for reasonable price, but there are many other sellers......

Klingspor, or Econ Abrasives.

[Pete Staehling]

Klingspor or Grainger come to mind, but I think they are generally readily available in part because I think that is a standard size for floor sanders.

Grizzly sells a 20' sander so naturally they have 20" discs in 2 packs. Here is the 80 grit: https://www.grizzly.com/products/Woodstock-20-A-O-Sanding-Disc-80-Grit-PSA-2-pk-/D1343

A quick search came up with 60, 80, 100, 120, 150 and 180 grit.
