Truck bed shell

I'm looking to pick up a shell. There are lots of choices out there. I do NOT want a softtop. What I'm looking for is:

* Ability to remove quickly. Most are held on with C-clamps of some sort. Are there "quick release" type of clamps out there?
* Lightweight. Goes with the first one. I'd like to be able to remove it by myself or maybe with my wife.

I don't need anything fancy, like windoors. I will only use it a handful of times throughout the year, so it will be off the truck most of the time. I currently have a tonneau cover, which I thought I could make work, but not going to happen.

Thanks.
