Ive been using Harbor Freight tools as a hobby mechanic (not professional) for years. Grinders, drills, sawzall, miter saw, air compressor, torque wrenches, shop press, etc. Very rarely do i have issues, and if i do i take it back and they swap it. They're at least a good option to get started in welding/grinding/etc for tools you might only periodically use. If you do use them, pick up a car magazine like Hot Rod or something, there's usually always Harbor Frieght one or two page ads near the back. 20% off minimum on any single item and often multiple free stuff (rags, lights, magnet trays, etc).

On a side note, have you simply tried calling LMC and explaining they may have sent you the wrong parts. Verify part numbers, make/model with them on the phone, and they may just send you a new kit since they possibly screwed up.
