So my husband and I have been discussing getting a backpack-type travel cage for Marcus. He is just in love with his Paradise Perch and Go travel cage--rather, he is in love with the fact that he can leave the house with us now--but honestly I think another carrier would be better for him, something we can really take him out and about in, comfortably, for longer spells. I know a number of forum members here have the Pak-O-Bird carrier, but I like the idea of the Adventure Pack a little better because it is a real cage inside of the backpack, and therefore would seem a bit stronger and more durable to me.
