Do you have a local store like Dick's or Sportsman's Warehouse? I would just go there and check out what they have. Plano and one other company make less expensive hard cases that will probably work OK, and you can generally get some of them in a shorter variety. They aren't as durable as a pelican, but are perfectly servicable.
Winchester also "makes" a line of aluminum-ish cases that are really nice and less than Pelican. They come in TONS of sizes, and are at most sporting goods places. They are the ribbed style with aluminum/metal edges & corners and buckle latches. They are pretty nice, but may be more than you want to spend.
I wish I could remember the brand of my large pistol case, but it's out in the garage right now behind my truck and I can't get to it without moving it. They are everywhere though, and good enough.
I think my rifle cases are Contico or something. *Almost* as durable as a pelican, really, but not quite. Bought them used off a previous landlord, but I've not seen them for sale anywhere. They are long enough for a 91/30 though––so not 36"!
