FYI; if you search molded Rifle cases on Amazon. You can probably find something that is damn close at 1/4 of the price. Some have preslotted foam cubes that easily come out instead of having to cut so that it looks clean and custom formed to your unit. I haven't 100% decided yet on what I want to do but this is another option. Some even have wheels and the retractable handle.
Here's one for $60...doesn't have the wheels but you can accommodate some extra pedals, accessories too.
