I bought an Eagle Rifle Case and Sniper Rifle Cover/Pad from LightFighter. The Eagle case holds one gun, which is slipped in like a letter into an envelope, plus four mag pouches and a flat pocket on the outside. The Cover/Pad is a three-fold pad with straps for a long gun, can be used for a shooting mat or to lay rifles on the bench/ground. It also has foliage loops, a drag handle, a pocket and cartidge loops for a bolt gun.
I have the same BlackHawk case Slacker has, likewise from C4iGrant. The main compartment has a removable divider for two rifles, or the "long" portion of a 3-gun set. The smaller outer pocket is for a pistol, and has Velcro panel and detachable/adjustable holster for a handgun. There's also a pocket for mags/targets/whatever.
Both BlackHawk and Eagle stuff seems well built. I could destroy either if I tried hard enough, but neither is going to wear out anytime soon. Whether you decide on hard or soft -side, make sure it has closed-cell foam that won't absorb moisture if you keep it in there for a while.
