This is a little larger than the Petco 36" - I like that.  I bought the double-door to give myself options in packing a small suv.  It has the typical plastic handles, which eventually break and are hard on my hands.  We found the shoulder strap to a garment bag and hooked it onto each end of the crate.  It works great to carry them.  Of course a couple ergo-type handles of tougher material would be great too.   If we get another dog, I will be buying another one like this.  Note:  we own golden retrievers.
