I think Eisenhower was a great man and a good President. But he gets far too much credit for his one brief comment about the military-industrial complex (which leftydee cited above). The fact is that he issued that warning in January of 1960, in his farewell address -- in other words, at the very moment when he would no longer have any responsibility for keeping the military-industrial complex in check.

As for the whole "land war in Asia" thing, he was concerned about the difficulties of that in the abstract, as were most military men at the time. But, revisionist history notwithstanding, Eisenhower was very much in favor of our military efforts in Vietnam, and advised Kennedy to increase troop levels and push on to victory there.

It should also be noted that Eisenhower was the man most responsible for basing our military strategy against the Soviets on nuclear deterrence (which subsequently evolved into the concept known as "Mutually Assured Destruction," or "MAD"). This was primarily a matter of economy, since basing nukes in Europe was cheaper than maintaining large standing armies there. There was much debate about this among military men at the time, and historians are still debating the wisdom of that approach.
