This is the older unisaw, around mid. 40's. The Delta 50-273 is made for unisaws, but will not work on the older ones.
So this being the case, what is the best for the older unisaw.
I looked at the Grizzly (Shop Fox) 2057A but some report it is not so good, trouble with the casters.
I am not looking to build one at this time.
Also to add, I do not have a 50" fence, just a 30, so don't think I need the long mobile base.
