I'm all about P2Pool... so I recommend:
http://limp2pool.fr:9022/static/
It's where I am pointing... it's not my own node, but I've been happy there for a long time.
.... there are other nodes too, just make sure they've updated. Also depends where you are as with P2Pool you should keep the latency low(ish)...
Eastern US
For the moment it appears the only ones that have updated so far are based in Europe. Might be best to go for a normal pool for now where geography isn't as important.
