Hi Pugh,
The Diamond "Smart" table differs in many ways from the Diamond "Pro". Other posters have given you some info. The "Pro" table also has a deeper shelf in the pocket. If you are looking for the best, get the "Pro". Be sure to have someone who cares set up the table. If you are near enough to New Albany, IN (Louisville), have them deliver and set the table up. Watch for events using Diamond tables. I'll bet Diamond would sell you one and deliver it for a very reasonable price. Will you be in Vegas for the BCA / US Open this month? Good luck!!!!
