It is a must have if you get the Skil Circular Saw, it is quicker to get good straight cuts than try free hand and correcting off line cuts even with set-ups. Try with scrap wood to get the method then it is easy.
Great tool, it is more for the good DIY'er. than a complete beginner. Unless you are aware of the power and weight. Does a deeper cut than cheap saws. I recommend you buy the Skil Guide-Rail as well with it as it is much easier and quicker to get long straight cuts.
Third in the set, can't wait for the rest of them. If you love the thrill and song differences of live music you will love the old concerts on these CDs. Don't expect studio quality, these are LIVE concerts warts and all. GREAT
