I have seen these very often in garden centers and big box stores. Usually they are in very bad shape (much worse than the other orchids there), overwatered... So I would only get only if it was a fresh delivery. I got one as a gift for someone, and when no one was looking I poked around to check the roots before buying it.
If you are reasonably certain that they are in good health, yes, I would get one (I never say no to an orchid!
), and repot asap!
I have to say that those mini phals are absolute cutsies!!
