If you look at the title, it says entry level full suspension 29er. $1500 is entry level for such things.
But is an "entry level" FS still a decent choice or do you need to spend over $2000 to get anything worthwhile? The Hei Hei, or any of the bikes the OP listed, seem like a decent bike, but I don't know much about the type of rear shocks they use.
