Original poster: "levi Mccann" <levimccann-at-hotmail-dot-com> I got to thinking about the use of a variac, but I came up with an idea. Why not use a Router speed control in place of a variac, they are much less expensive, have the same power ratings, but at a fraction of the cost. Does anyone have any ideas, pro and con for the speed control vs the variac??? Input would be greatly appreciated! Thanks, -Levi _
