M.6.
I'd check Once Upon a Child, thrift stores, and your local freecycle/craigslist for an item like this before I'd buy new. Lots of folks use these kind of baby items so rarely they are usually in really great shape. When you are done, please consider donating to a shelter or church for a needy family (my New Year's resolution - buy used when I can and donate to charity if in good shape).
Good luck!
