The SurfPrep 3×4″ Electric Ray is overall the best sander for refinishing furniture because of its versatility, small size, and how little it vibrates.
This Ryobi detail sander is the best budget sander because you can attach a vacuum to it, and it works with SurfPrep sander’s foam pads.
Before I bought the SurfPrep sander, I used this Dewalt orbital sander when I needed to remove paint or stain from flat surfaces
The Festool RTS 400 REQ sander is one of my new favorite sanders. It’s a powerful and versatile sander that is easy to use.
