I'm wondering the same thing. I (46)am going to buy one for my solo trip in September, then take him along on the family trip in October. One good thing, if you don't want to keep him, you can sell him on ebay for just about what you paid for him. I saw one go for $55 a couple of weeks ago, and I think they retail for $60.
Another option is to rent him, I think for about $10. As far as I have heard, if you like him, you can buy him and they will credit you for the $10.
