Certain tools like spoke wrenches or a crank puller don't really have an equivalent tool...while on the other hand I refuse to spend money on a chainwhip as vise grips and a leftover section of chain do the same thing. However, I will say that on most tools that are similar a tool from park is much better than a tool from harbor freight. Quality from Harbor Freight is just not the same as tools from say Cornwell, snap-on, etc. You get what u pay for.
