Short version: Is a 56" long treadmill belt too short for a 6' 2" tall person to run on?

Long version: I'm currently treadmill hunting, and have a question regarding belt length. I notice that newer treadmills tend to have 60" belts, although not all. A lot of nice treadmills have 56" belts, so I'm wondering (and I would never ask this in any other context, but;) would I really miss those 4 inches?

The treadmills at my former gym were commercial Precors with 60" decks, and I never got near the back, but I've seen a few good deals on used home Precors, and they all have 56" decks.

Thoughts? (I'm not married to the idea of buying a Precor, but have seem some attractively priced units locally).
