I know the Ridgid has captured most of the interest because it works on inside curves - I need to get one too for the next project. I will add my 2 cents to Mike’s comment on the big HF disc unit, because it’s solid, powerful and pretty bombproof. If your shop has bench space it can be worth having.

The 12” disc excels on outside curves, and for taking off material FAST. And the simplicity of a single purpose design contributes to stoutness and durability. Ok, The aluminum bed is the weak link but the motor is powerful and the unit is heavy (40-50 lbs) so vibration minimal. I would love to have a higher quality unit, but I just set mine up with a square at 90 degees and leave it. Dust collection via 2” port is excellent with a shopvac. It cost under $100 and has far outlived its that price. An 80 grit disc is general purpose and alternates with 120 depending on wood species.
