So here's my report from Cabela's (and from McBride's, but their selection was very limited, so I just headed out to Cabela's).

I was looking for a case that held at least two long guns (>40") without breakdown, was lockable, flight-proof/ready, and had wheels. On top of that, I'd prefer that it not be so heavy that I have to pay extra if I some day have no status to get me that extra little wiggle room on weight.

Cabela's had a lot of hard cases, but there were really only 4 (more with some variations on models) that met all those descriptions:

SKB: I like everything about the SKB cases (they had a 2 gun and 4 gun case) except the locking mechanism. I mentioned previously that Cabela's had a case that had TSA approved locks but no other way to lock it -- turns out this is it. It's a hard molded plastic case with 4 latches running down the front. Two of these latches have integrated TSA approved locks and the other two don't lock at all. In addition, there's no secondary hasp or any other way to lock the case other than the TSA locks.

Pelican Case: This is actually the case I bought (model 1750) (I already use a few Pelican cases at the office for traveling with AV and computer equipment). The foam for the Pelican case isn't as good as the others (flat instead of egg crate -- it seems to me the egg crate might prevent the weapons from shifting in the case better -- then again the foam that is provided is extremely tight, so maybe that's all you need to prevent slipping), but all of its other features are great: watertight seal, low profile, good durable handles, 4 strong latches down the front, extremely durable injection molded plastic with rounded corners to prevent anything from getting bashed in. Best of all, it has two integrated lock hasps with no moving parts -- they're simply parts of the flange outside the seal but protected by the adjacent latch and reinforced with aluminum. On top of that, I found when I got home that the flat wide form factor allowed me to fit 3 shotguns (one is admittedly a small .410) plus a few choke tubes, two small handguns and an extra clip. That's more than I realistically plan to pack when traveling, but that comes in at under 45 lbs, with locks.

Flight Proof: This definitely had the appearance of being the strongest. This case was a mixed media, if you will. Some hard material of indeterminate nature on the sides (plastic; vinyl covered fiberboard), with aluminum beaded edges and chrome-balled corners (think of the equipment cases from touring rock shows). They even had the butterfly closures with built in hasps and recessed spring-loaded handles. All in all, this was a really nice case. But it also weighted about 40 lbs for the single gun model they had in stock. Even if the two-gun model weighed the same, you're looking at >50 lbs when packed.

Cabela's Bullet Proof: This case was alright. It was all aluminum with each of the two halves being formed from single sheets, cut, bent, and welded to form the case. The biggest problems I had with this were (1) the corners which the case looked destined to be dropped on and which would surely have then knocked the case out of alignment, and (2) the hardware, all of which was riveted on and none of which looked all that substantial (latches, hinges, and handles).

Here are the 4, in the order reviewed:
