Spamhaus: yes. Use zen.spamhaus.org (you might end up needing to pay for it, and use a local cache, if you're a heavy traffic site, but, frankly, it's worth paying for).
We use Spamhaus here with their datefeed service. Our two filter servers reject an average 3.2 million messages every 24 hours with using zen.spamhaus.org.
