In the near future I'm planning to add some electric to my soon-to-be workshop in the basement which is about 50 feet away from the main panel (new 200 amp panel). I have a bunch of toys... um... I mean tools. Your basic wood working tools plus an arc welder and my wife's kilns... They all run on 110v, but who knows maybe I'll get some 220v tools soon.

So my question is; is it worth installing a new subpanel in my workshop or run several new lines as needed from the main panel? How many amps for the subpanel? Also what type of wire and\or conduit would be needed to be run to the subpanel?
