Harbor Freight usually has less expensive and lower quality tools. They
may be fine for some uses, I buy them on occasion, but keep that in mind.
It is difficult to compare drills based on specs. Find someone who has
one and ask them. It appears you do a lot of work, I would look for
quality, not price. If it is something you are going to use a lot, it
generally pays to buy the best quality tools.
