Those sanders look to be excellent vfm. I’d be interested in the dust extraction efficiency as my workshop is fairly small and getting the dust removed at source is a primary concern. If it means spending the money I’ll do it, just wriggling at the moment as 500 seems excessive !It was my Hyvst sander that Keith was using in that video! There's a very similar Sealey branded version that's not much more than I paid for the Hyvst, after shipping etc... that won't have the warranty concerns. It's a great sander, been using it regularly since buying it without any issues, and was using it today.
