I am considering a trip to New Zealand from the east coast (USA) but are starting to have second thoughts. Why?

I do not have the miles, FF status, or funds to go business class or first class.

Last time I went as far (Singapore) I was unable to sleep for more than 3 hours a night for almost a week because of jet lag. Those were some long nights!

Is there anywhere 10-12 time zones away that is really worth sitting in coach for 21 hours and the jet lag?
