I have all 21 volumes of X-Factor, and yet I don't have Messiah Complex in trade or hardcover, which means in collected editions I don't have the entire X-Factor experience.

Why don't you buy the Messiah CompleX TPB and slot it between X-Factor volumes 4-5? Bam, you now have the entire X-Factor experience.
