I use the Miller which is far superior to a HF model.
Reason.
1) The Miller has a replaceable battery, the HF doesn't. If the built in battery fails the hood has to be pitched. This happened to a friend that had a HF hood. He now owns a Miller.
2) Parts are easily found at any welding supply co. that sells Miller welding equipment.
3) The Miller hood has a slot to receive a Mag lens if you need it,(I do) the HF does not.
Buy the Miller, you'll be glad you did.
