TP 2 Case that's easy to remove

[hceuterpe]

I've been looking high and low for a Sprint TP 2 case which:
1) Isn't made out of aluminum
2) Is easy to remove, so I can access the back cover for the battery microSD slot, etc.

Every case I've found so far is either made out of aluminum, killing my signal, or made out of hard plastic, which is going to break apart very quickly with repeated removals.

So, does anyone know of a case designed for easy access to the battery cover?
