Baldor look shockingly good and equally expensive.
Probably should have said nice but not too pricey. It is for our community workshop here. I'd like something that could have buffing wheels added to it for polishing duties.
Clarke would be my go-to for home gamers. If you're serious about polishing, get a specific polisher, the extra clearance is worth having, and breaking down a grinder every time you want to polish something will annoy you and the people who want to use the grinder.
