i am in line with everyone else... save your money... i have one and ive hardly ever used it... i think its one of those tools that its nice to have when you need it... but if i could do it again it would get a nice jig saw and a router that should cover about everything a dremel will do...
Routers are amazing tools If you get a router I see no need for a jig saw. I'd get a circular saw instead. Remember to use very good safety rules.
Like turning off a circular saw before you leave the cut(Suggested by Bob Johnston,50 years of carpentry experience, in a Bob Vila article). You'd be amazed how many folks even experts ignore this simple step. All it takes is tripping while the saw is running and your dead.
Remember to get good gloves(Splinters suck and wood can cut your hands.), safety glasses and ear plugs.
We want you got be shaking hands, watching movies, and listenign to music for years to come.
