Whatever you buy, make sure it is a Dremel. Loads of imitations out there, and all they seem to imitate is the sound of money going out of people's wallets when they break!!
I've had two (mains) Dremels in 30 years. The first one lasted 28 of those years, and finally died when the commutator just ran out of copper! Must be all those years making slot cars - cutting brass plate and piano wire, the metal dust was profuse! My latest one gets less use, so maybe it'll outlast me!! Arguably the best tool in my shed when it comes to doing work on things in the house, and RC. HTH
