First find out if it removes metal fast. I have used Chinese grinders very similar to the one pictured and they didn't all perform the same. Some had crummy wheels and some had weak motors. Others worked quite well. As a machinist with about 48 years experience with metal working I have seen plenty of grinders. I myself have three Baldor grinders which are all excellent. I have two Chinese grinders, one which is great and gets used all the time while the other one is junk. I also have a Taiwanese grinder that I lengthened the shafts on and use for a buffer. It is a little under powered but works fine for buffing small stuff, which is why I bought it. I really need to get rid of the junk grinder. The wheels don't stay sharp, it is under powered, and it shocked me the last time I touched the motor housing. I cut the cord off so that nobody else would get shocked. That was probably 10 years ago. I need to get rid of it.
Speaking of Baldor grinders if a person can find one used for a good price they ought to buy it. My oldest Baldor was probably made around 1935 and my other two I would say 1960 to 1980. All three are virtually vibration free. This is because they are not only balanced mechanically but also electrically. They run very smooth. So when grinding tools it easy to get a very good finish. My oldest Baldor had cast wheel guards. The one on the right side was partially broken off when I got the grinder. I removed the rest of it and mounted a diamond wheel on that side for grinding tungsten electrodes for TIG welding. The really smooth grinding action means I get perfect grinds on my electrodes.
