I bought a Scicon hard case last year and don't regret it. It was a toss-up between that and an Alan, but a discount code from ProBikeKit swung it for the Scicon. I'd hired the Polaris hard case before that, and wouldn't particularly recommend it. The rings which you hang the frame from a weak as - one bent out in transit, meaning my hanger got bent. yaaay. Did learn to over-protect that part of the bike next time I flew, at least.
