Im Looking at getting a new bench sander, My grinders suck but I can live with that, I've a couple angle grinders that work well. Can anyone recommend a good manufacturer to look at. Ideally id like a belt sander but im open to ideas. The power in the sanders ive seen is usually 500w or less. I need it to be single phase. Also would it be worth looking at a combi grinder/sander style thing?
