Very cool to know about the burley history, thanks! I've been considering a child carrier used, looking at craigslist, but I like that I can fold the travoy up and store it inside in a tiny space in the bag. The other advantage is that I could roll it into Costco and put the 40 lb bag of dog food on it and not have to lift it again. It seems to keep value very well so I could sell it without much of a loss if, for some reason, I found myself not using it. I would sell my Xootr crossrack since I would not need it anymore. Finally, it attaches to the seatpost, is very light, and would work with a rear mounted Shareroller (coming this fall).
