After reading the given threads, im sure by now, you should have an idea on what type of camera you want.
For travelling, it wise to get mirrorless cam due to it small, compact and light, unless of coz, u dont mind lugging heavy DSLR.
If you opt for mirrorless.. go for Sony NEX, Samsung NX, Olympus Pen, Panasonic G series or for new entry level DSLR.. you can go for Nikon D3200, Canon 650D, Sony A57 or Pentax K30.. All within your budget.
As other mentioned.. all these cameras are good and capable cam, they have pros and cons over the others.. Read their reviews, shortlist them, go to the mall and hands on, see which one fit in your hand and get that..
If still confuse.. get Sony RX100 or Panasonic LX7
