Hi there, thanks for the question! For hand sanding machines, I recommend checking out the Ryobi 125mm 380w Random Orbital Sander for R829 and the Black & Decker 125MM 230W 230W Random Orbital Sander BEW210-QS for R449. These random orbital sanders are versatile, powerful tools that will make quick work of sanding without leaving swirl marks. The random orbital motion helps create a smooth finish. They're also cordless options like the Ryobi and Ingco sanders, allowing you to sand anywhere. Let me know if you need any other details on these top-rated sanders!
