Best Dremel/Tool for cutting hard plastic and/or metal

Posted in Custom Workstation

Hey gang, a little deviation from figures here. My hobby is customizing 1/16 and 1/18 scale plastic and die-cast cars, specifically batmobiles. I need your recommendation on a good, reliable power tool for cutting MOSTLY hard plastic in small areas (I.e. cutting out the 'headlights' on a 1/16 scale plastic batmobile so my LEDs can shine through), also for drilling holes into metal (I.e. the 1/18 scale die-cast Barris 1966 Batmobile).

I am assuming that the Dremel 300 would fit the bill - but do you folks have any recommendations on dremel/other make power tools that are better, and if so, what type of bits/parts I should be looking for?

Also re: dremel, what is a good part for sanding down the edges of small holes/areas that I've cut out of a piece of plastic?

Thanks *much*,
