What's the problem with infinite regress?

A large number of philosophical arguments for the existence of God seem to rely upon saying something along the lines of 'since there cannot be infinite regress...' to prove their point. I don't see why it should be so obvious that infinite regress is impossible. Can someone explain?

It's not that no infinite regress is *possible*, it's that any infinite regress fails to serve as a justification for the conclusion.  If each step in your justification appeals to the truth of another claim, whose justification requires an appeal to the truth of another claim (and so on), then at no stage in the argument is the truth of any of these claims established --  although they may well all *be* true.
