Thanks, Charles. I've that Grizzly's BS comparison chart up on my screen a number of times trying to ID the different features that will make a difference for my intended purposes. (separate models just for the sake of a color change is a bit too much IMO). Cast iron wheels and trunions, along with the 'better' bearings were my starting point but I'll go back and check out the fences.
And your point about the same factory churning out nearly the same saws except for color and pricing is definitely on my mind.
