Maybe it’s just me, but I am puzzled why anyone would still buy a table with no ball return. To me any added expense would be insignificant compared to the constantly annoying hassle of emptying pockets over a lifetime.
Haven’t played on any of the newer examples, but I WAS initially a bit disconcerted by the loud report of a pocketed ball dropping on Greg’s first ball return prototype mechanisms, though over time I have found the sound to be rather reassuring (like the sharp ‘pop’ when you win at pinball).
And those of us with a sore back, we don't have to keep bending over all the time to get the balls out of the collection spot. That would be a lot of bending over during a day.
