According to these prices
it should not be difficult.
I do not recommend Harbor Freight for most of what I see them offering.
Also, I once had the audacity to write them a letter with questions about their $300 chop saw which was a gift to me. What I got back was sarcasm, arrogance and ridicule.
And it turned out that the answer to my question was not all that difficult.
I doubt they know anything about their products and I doubt they want to know, either. It's "take it at our price or leave it, no questions welcome."
And I suppose they are profitable [until they get sued for a product liability issue].
