Thanks to everyone for your replies, I am glad you realized that I was referring to the Dewalt 788. I don't know where "7800" came from (senior moment maybe)?
I think I would be wise to get a new 788 since there is not that much difference in cost. I started to purchase a new one from Grizzley.com for $499.00 which includes stand and light. I did not because I read several bad reviews about Grizzley's customer service and problems people had when they tried to return new saws that did not work properly. Has anyone had any experience along these lines with Grizzley?
Again thank you for the valuable information that the members of this forum provide.
