I wouldn't worry too much. I've got 5 bikes - and the position is about the same on all of them:
one bike is a size too small (huge discount at the time, but I wouldn't repeat that decision making process)
two that are half a size too big and small respectively (which harks back to a post from smallfurry pointing out that some models just will not fit due to available geometries)
two that are the right size, one of which fits like a second skin.
I probably don't need to say which are the best to ride ;)
