You would need to check it over for loose pivots and worn parts. Personally I would pass on it for $200.00, unless it came with a lot of wheels in the sizes that I was looking for. My Foley gets used last, it is slow. It can do a nice job but it seems to require a bit more operator care than the others that I have. Often see them in the $50.00 to 100.00 range with a couple of wheels.
I have a 511 knockoff grinder that TSC sells for around $150.00 that I hands down prefer to the Foley that I have. Way faster, larger wheel and it holds the tolerances better. Wheels are everywhere for the 511 types. See the grinders used for the $50.00-100.00 range every once in a while. Paid $50.00 (store return TSC)for mine and needed to put a washer on it, replaced the wheel. Nice grinder.
The Harbor Freight grinder is not as nice as the Foley, however I would consider it similar in effect. The Foley 308 allows for the swing arm to be angled, almost never need to change this. Not sure if it allows the vise to be moved, even if it does almost never need to do this. Some will argue that it is easier to do depth gauges with the Foley, it depends on the condition of the grinder and skill of the operator. Personally prefer to depth gauges with a file and guide even with multiple grinders, and the 511s do the depth gauges faster and easier as well.
