I picked up three $9 angle grinders, from Menards (on sale), several years ago. One has a masonry blade, one has a metals blade and one has a diamond blade in it. They are always ready to go and don't take up much space. I'm a handyman so the tools get a lot of use.
My pretty yellow Dewalt angle grinder sits on the shelf, unused, because I don't want to get it messed up with brick dust, metal filings or tile shards.
Chosen wisely, the HF stuff can be a good buy for light to medium duty.
My cordless tools are Panasonic and Dewalt, my corded and air tools are Bosch, Hilti and Porter Cable, but they're in use every single day.
You might think I haven't contributed much to the world, but a large number
of the warning labels on tools can be traced back to things I've done...
