I have one of the panelsaws you saw in Lowes that we brought back from a plant in Mexico.....don't ask, it was a disaster....They work great for rough cutting.
I was on the web site of the company the other day
Safety Speed Cut
and I see they are offering a router, but it is horizontal and looks to be 2-axis not three.
If you are looking to convert a panelsaw to a router, I can sell you one cheap! It only has a few thousand miles on it and was only drive on Sunday to church by my grandmother!
