Summary: 

The Oracle clamp is particularly effective, I think, because of the spacer
under the centre of the record and the fact that the clamp exerts
pressure only in a circle at the outer edge of the label area.  When
it is screwed down, the record would be flexed in a manner that would
tend to apply pressure against the mat over most or all of the record
surface due to the vinyl's springiness.  

I haven't seen an aftermarket clamp that works in the same way.
Also, the Oracle depends on the turntable having a threaded spindle
to screw the clamp onto - could a clamp that just uses a chuck develop
as much force?

(When I was shopping for a new turntable last year, I considered an Oracle,
but eventually decided it was just too much money for me.)
