I've used both a collapsible mesh basket and the Orvis plastic bin
with the cones in it. The collapsible mesh one, while convenient for
travel, does not work very well. The Orvis one works great, but
takes up a bit of space (not as bad as you think as you can stuff it
full of fishing gear and other things you are going to pack). I
travel with the Orvis one now. The collapsible one might work better
with some stiff heavy mono, weed whacker line or zip ties in the
bottom to keep the line from tangling, but then it would be as
portable, unless you removed the zip ties every time you packed it
(not that big of a deal - zip ties are cheap).
Here is a picture of a home made one where you can see they used zip
ties. You can make one yourself with a small plastic dishwashing
bin, an old wader belt, a drill and some zip ties or stiff heavy
mono. You can even put a bend in it like the Orvis one if you have
access to a heat gun.
