Go to another store.

The case you want will come with foam in the lid, on the floor, and a center-sheet of foam comprised of removable 1/2 X 3 inch blocks. OR a solid center piece you can cut with an ELECTRIC knife. Just don't let the wife see you use this 1970's hierloom for your hobby.

The one you are describing is fine for tools and such, but you will have to line it with foam yourself.

My 1st case was a plactic pistol case..worked great.

The goal here is to have foam on all sides of the TX, and not allow it to move in the case at all.

I know they have them at Harbor Freight, but I dunno if Harbor Freight exists in your area. Google it. these cases come from China, (surprise), and they are available for $20 to $120 for the same dern thing.

Good Luck!!
