We had one at 28 1/2 weeks. It was a great experience, however, baby wasn't that co-operative, so the pictures/DVD are perhaps not as great as they could be. I'd say it depends how tight money is - if you can afford it, go for it, if the money is tight to the point that you'll worry about it if you go ahead, I'd say to cancel - although lovely, it isn't worth any financial worry.
