we have the rainforest cradle swing (has been replaced by the precious planets) and i could not rate it more highly. it has been a life-saver. i use it everyday- have used it for both kids. ds1 used to actually sleep in it, ds2 hasn't had a sleep in it yet but is happy to sit in it for an hour while i cook/clean. it's fantastic.
both my boys have only liked the side to side cradle motion, so i would definitely get the precious planets cradle one if i was going to buy one brand new. we got our rainforest one during a sale at toys r us.
