I've been using the Boyt takedown case and like it. Much better than lugging around a heavy aluminum case. If you can live with a full length case, Beretta makes a great case that will easily hold a 34 inch trap gun.
I like the Boyt soft case for 52" pump and semi-auto shotguns for my 870's and 1100/11-87's.
They run in the $80-$90 range plus tax but are well worth it. They have a tough canvas exterior and are well padded with cotton interiors. They also have massive brass zippers and leather carrying straps.
I bought my first Boyt case at the Grand a few years back for half price from a bargain bin outside one of the vendor buildings (it had a Smith and Wesson logo on it). I liked it so much I bought two more the next year at regular price.
It will fit any of my guns. Made with real leather and no way the zipper can scratch your wood.
I also have the Cabela's case pictured above. I like it better than the Boyt because it has a plastic zipper and won't scratch your stock. I've been carrying my Ljutic around in it for a year. No problems what-so-ever.
I like the take-down cases because they fit into the trunk easier.
I looked at the Cabelas case a few years ago when I was shopping. At that time there were numerous comments on their "customer opinions" section complaining about shoddy workmanship, poor stitching, defective zippers, etc. Perhaps they have cured all the problems. Relative to the Boyt, which I own, the metal zipper is an issue, and can mar the butt of the grip if you're not careful. Otherwise, its nice and a heck of a lot lighter than the Americase.
WIC- I went through this same search for my 34" unsingle so I shouldn't have to take it apart each time. The 54" Boyt bag did not fit this size gun- I had to return the bag. I finally found the Beretta HP soft bag in 56" which fit perfectly. It is also a superior bag-very well made.
