The only effective counter against a proper DDoS is to bring more bandwidth than your attacker has.

A small site is unlikely to attract a proper DDoS, but will get hit by the usual misbehaving web scrapers, broken clients in a silly loop (I'm looking at you, iTunes) and keyboards with super sensitive F5 key. In those cases, serving an occasional 503 might work better than the alternatives.
