We had a secondhand (or more like fifth-hand) Baby Bjorn, sold it on for basically the same as we paid. Both babies really liked it. Practically, we found advantages of that style were: adjustable angle as baby grows, lightweight so easy to move around the house/garden, folds flat so easy to tuck out of the way and to travel with, and very easy to wash (pull off cover, put in washing machine, essential with our refluxy second). Some of the dupes may have the same features, though.
