depends what you want to do but if you dont need the lens changing ability and so on of a dslr, i recommend the Panazonic LZ8 compact camera. Has manual settings and a pretty intelligent auto system. The charm is that its pretty good for night shots as well. Works with AA batteries so more or less covered if you are a traveller. I got mine for less then $170 with free gift at Mustafa warehouse sale last week.
depends on where you buy
2nd Market or coming PC Show should get you quite a number of choices high mega-pixels digital point-and-shoot cameras going for sale
dont expect you can get a pretty decent camera with that price... bear that in mind
