Dremmel stands behind there products!

I remember back in the 1970's matching my 273 cylinder heads with the intake manifold gaskets using an electric Dremel tool and various attachments. It got very hot, but never quit on me; polished the combustion chambers, too. Now I need a similar tool again, but read many reports on the internet reviews of the motors burning out. Is there a similar type tool out there that has a better reputation/better quality build? Going shopping tomorrow. Thank you.
