|Although I had one stay-dry in my stash, if I were buying, I wouldn't get more. I used a fleece liner in each diaper to keep baby dry and to make clean-up easier. It does the same thing, but then I had the option to remove that dry feeling when it came time to potty-train. I think that many ME users feel similarly decide that fleece is cheaper, and you have more flexibility.
All that to say, the stay-dry is a great diaper, of course, probably just less popular, so less easily available to buy used.
