They seem pretty hard to find and look at before buying, and as far as I can tell none worth buying is cheap. When we visited the ABA offices in Colorado Springs last May, I liked the one they sell, bought it, and am happy with it. It has lots of useful extra pockets, and just meets the length-width-height dimensions for airline carry-on. Scopes fit in it, but as for one's tripod, some do and some don't.
