The good thing about starter cameras is everyone starts at this point and then gradually progresses up the body ranks until they hit a model they desire or feel meets their expectations.
The good thing for you is that these people re sell their starter cameras and you get a chance to pick up a bargain! The models quoted above can be found in abundance on hear or in 2nd hand camera shops!
As said previously though, have a feel of them first before you commit - yes they all do roughly the same but they do not feel the same when in the hand.
