I think Jim Jeffries is sold out, but if you can get a ticket...
The international acts are a bit meh this year imo. Russell Peters is probably the stand out. Ari Shaffir is a funny guy on podcasts but I'm not totally sold on his stand up.
(That's not to say the international guests aren't funny, just not my type, or I've never heard them)
It's the year to load up on local acts I reckon.
Off the top of my head, check out:
Steele Saunders (He has a stand up show, and live recordings of both his podcasts)
