I can't speak to comparative pricing, but I helped some friends pack one up for a move from Somerville to California, and it was cost-effective and more pleasant than with the time pressure of loading a truck.

About the one caveat I'd have is that you shouldn't expect one to have solid walls you can pack things in against; there's framing and then a sturdy outer fabric cover. (They are also, thus, far from secure, but fine for general household foods.
