My dog loves to sleep in his create so I wanted to purchase a new one for him.  I found this one on Wayfair.  He LOVES IT!  Very sturdy material.  Easy to put together and quickly collapses for travel.  He'll be riding in this on our 22hr trip to adanibel FL.  Can't beat the price! I purchased a large.  He's 65lb and its a little big, but I like that since he sleeps in it every night.
