Do you guys usethem alot or are they as versatile as the makers make it sound? I need to buy one for a project on my stang (have to do some cuts to the metal). And a Dremel tool sounds like what I need. Now when I go to the Home Depot they have a gigantic kit for like 99 bucks that comes with all kinds of stuff. And by far is the best value. Or I can just buy the tool by itself. I am all in favor of a deal, but I dont want to buy this big kit if it is just going to sit in my garage hidden. Do you guys with them find them very useful?
