Tall and good looking

There's an interesting discussion of height and selection at Razib's blog Gene Expression. I can think of lots of plausible tradeoffs related to greater height -- increased calorie requirements, perhaps not so adaptive for females, effects on metabolism or other body systems, etc. But what about facial attractiveness or symmetry? Every so often I see a really good looking face and the effect is very striking. Surely there are lots of benefits from this, but are there any plausible genetic costs? I would guess that evolution can tweak facial bone structure without affecting the brain or other bodily systems... If so, why aren't we all much better looking? :-)
