I use a Skil brand for aluminum when needed, same one for wood as needed. Only thing about them that I hate is the same thing I hate about sawzalls. They beat the heck out of you. Used the miter saw the other day tinkering about the shop and it hung up a few times and beat me like a rented mule. Stop, take a breath, "don't throw it across the field Shawn, don't throw it across the field". It survived the work, was called every name under the sun and was stashed in that "I'll forget I even have it place" right next to the two sawzall's I think I own.
