New deck build: random orbit or belt sander?

Hey everyone, I'm building a 12x16 treated pine deck and need to sand the surface before staining. Should I get a random orbit sander or a belt sander? I've got a tight budget but want good results. TIA!

I'd go with a random orbit for deck sanding. Belt sanders can dig in too easy on softwood and leave gouges. Plus you get swirl marks if you're not careful. Make sure to wear a respirator—treated pine dust is nasty.

Random orbit all the way. Get a variable speed one (5-amp min) with dust collection. For a deck you want 80 grit then 120. Belt sander is for removing material fast, not finishing. Also check your local HF for cheap packs of discs.

Actually, for a deck I'd use a belt sander with careful technique. You can remove mill glaze faster. But get a quality one like Makita or Bosch with a soft pad. Random orbit takes forever on that many boards. Use 80 grit belt then hand sand edges.

Random orbit is safer for a beginner. A belt sander can ruin your deck in seconds if you linger. Get a 6-inch RO sander with hook-and-loop pad. Use 60-80 grit to strip, then 100-120 to finish. And don't forget to countersink screws first!
