You can get regular bassinets everywhere, and they're pretty much all "better" and "cheaper" but none will have the function the SNOO has of rocking the baby in a certain way, along with a certain sound, that is claimed to mimic the movement and sound of the womb, and is clearly extremely calming. You can do it with just your hands using instructions from "the happiest baby on the block" video, also made by the owner and inventor of SNOO.

If you can afford it, get a plain untreated wood crib/bassinet with a natural fiber flame retardant free mattress. I posted elsewhere in this thread about the theory that flame retardants might contribute to SIDS, and the plain wood is based on the fact that kids will chew on it, and get particles of paint or plastic in their mouth otherwise.
