if a person only had money to upgrade either just the sander or just a dust extractor which one should come first ? I have a simple $100 ros that works and a shop vac - been looking at festool 125 and either a harbor freight dust extractor or Rockler dust extractor but can’t get both at the same time. need to sell a few more things first . so is the sander more important or dust collection? right now ? #diy
