Pros
- The 11.0 amp motor and 4x24 belt eat through hardwood like nothing else on this list.
- 1,640 SFPM with a wide belt means you cover serious area fast.
- Tracks accurately despite the size.

Cons
- At 13.2 lbs, this is a two-handed tool and you will feel the weight after 15-20 minutes.

- At $130-170, it costs 2-3x the budget options.
- The 4x24 belt size costs more per belt than 3x21.
- Overkill for small furniture or trim work.
