Complete O&M

Dana Simpson just released The Complete Ozy and Millie in a two book set! This is fantastic news for those of us who adored the series, which is to say "all sane human beings". My only dilemma is this - do I get the paperback, which satisfies my much-worn sense of frugality, or the hardcover, which satisfies my fanboy jubilation? (Not that it's much of a dilemma, the answer is obvious.)
