Country Cage: A getaway home for our CAG

[FirstPenguin]

I currently live in a major metro area and am within a short enough distance of family that my girlfriend and I go visit often. With our current bird we have one or two smaller cages we leave at the homes we frequent the most. We call it her country cage. It makes packing just what we need for a weekend, and heading off really easy. Now we're in the market for a similar cage but for our soon to arrive CAG. I want something bigger than one of those suitcase sized travel cages, but not so big that I can't pick it up and move it to a different room or place it in a car to go somewhere else. They'll need to spend a few hours at a time in it if we go out. What would be appropriate for a CAG?
