Hell, even the fact that an electron or photon can only be described by a purely mathematical wavefunction sits better with me than saying that a string, a physical entity, is as small as it gets and is comprised of nothing but itself. I think I would feel better about strings if I thought about them as points of vibration giving rise to particles/forces rather than an actual "thing", per se.
A point that vibrates leads me to the question: what is doing the vibrating? Even if it is posed that these strings are made of something smaller, I prefer that the smallest part, at whatever point in the search for the smallest part we are at, is still made of something. I think that while string theory complicates some things (dimensions?), it is also in a better position to combine micro and macro physics for a reason. Ultimately, that reason is having a smallest part as opposed to having a zero point.

Again: big bang could not have started at one point. Just doesn't make sense. ;-)
