The Delta is a nice saw... yours looks a lot like mine, except my motor hangs underneath... I've added a Grizzly riser block to mine, so I have a green block in the middle of the frame... it made the blade a 105 inch blade.... only problem I've run into is the guide bar for the blade guides is smaller then the Delta guide so if I want the blade guides lower closer to the table I have to make sure the guide bar is shimmed well to keep it from turning... mostly I use the original delta guide and just don't lower the blade guides below about 5 or 6 inches... but the saw has served me well over the years.
Carter guides would be desirable on the saw, but I've not found them for less than about $130... out of my budget.
