Where is the best place to get tickets for the Joshua/Klitschko fight?

I am thinking of coming from the USA to see the fight, and there seems to be a large variety of different ways to get tickets. Which one is the best?

Club Wembley
Matchroom fight pass (this is currently shown as being out of stock)
Coach Packages
Stubhub UK (in the USA, stubhub is a resale ticket service-with prices higher than face value)
wembley stadium.com

Thanks for your advice!!
