I also am using Amazon for a baby registry. (You can set up a registry separate from your regular wish list, too.) I have been pretty impressed with the variety of items - organic clothes, natural toys, natural bath products, slings and carriers, etc - and how many are staying in stock. I know sometimes, with 3rd party sellers, especially, items will drop from stock pretty quickly and never come back. But, the vast majority of what I've put on my list is still available, a couple of months later. I'll keep checking as we get closer, but I've been quite happy with it so far. AND I can put things from other websites on that list, too.

I have used TheThingsIWant.com for from-anywhere wishlists in the past, and have liked them, too.
