I have a really old Burly that I got at a garage sale for $10 that I used to use for cargo hauling until I got my Xtracycle. Never put my kid in it (nor would I, seemed very uncomfortable for him). For my son, I bought a CoPilot Model A (retail is ~$250). Seats up to two, comes with back handlebar and front wheel for using as a stroller. Not sure why someone would want to drop the big bucks for a Burly, doesn't seem like they are a whole lot more rugged (or lighter, or cushier, or...)
