Perhaps this set of fossil skulls will help you. Creationists disagree amongst themselves on whether each one of these skulls are ape or human. Mainstream biologists say they are transitional between historic apes and modern human apes. By definition there will always be a "missing link" between what we find because the fossil record will always be incomplete. But the gaps get smaller and smaller.

My use of the term "missing link" does not refer to the transitional form per se, instead to the traditional "where did we split from the apes" (which by definition would also be transitional I guess :-) ).

I concur that the fossil record can never be "complete" - which neither proves nor disproves the theory of evolution.
