Hello..Ok so where should I go now?

Greetings fellow travelers! I'm new to this forum so I'd like to introduce myself. My name is Orlando and I live in the San Francisco bay area. I've recently caught the travel bug. This past year I spent a couple of month backpacking in South America. One of the best experiences of my life! Had the chance to hike Machu Picchu, party every night till 6am during carnival in Salvador and Rio, spent 2 weeks exploring Buenos Aires, and saw the beautiful waterfalls of Iguazu Falls. Since I've returned from my trip all I can think about is how to save up and backpack all over again. I'm on a tight budget so my next adventure will have to involve a lot of hosteling and couchsurfing. So I'm asking my fellow world travelers, where should my next backpacking adventure be? I've always wanted to go to Europe, but I heard it's really expensive. Some have suggested New Zealand and Australia. Asia also appeals to me. Any suggestions?

i could discuss about South America with with you forever!!!
I've been twice to Brazil and can't wait to irganize my next trip.

If you're on a low budget, why not try India?! I think it would be a spectacular trip, and you will be able to save if you want...
