I have a 15 year old no-name 10" that works well for both wood and steel. If I were to buy one today for wood working it would be most likely a DeWalt with a slide motor/blade. I use a 12" version where I volunteer at a theater doing carpentry work and it is slick.

One question - do you really need the big one for steel or will a 10" work for most of your work - the price goes up substantially - and if you are cutting steel, an inexpensive saw with a cut off blade will save you grief as the entire saw takes a nasty beating from the very hot chips - and a damaged/destroyed $350+ saw vs a $75 Harbor Freight.............is more then comforting
