Has anyone found and bought a decent (flip) case for T90?

I really like the convertible cases Case Techworks make
for T180/270/300, where you do not need to remove
flip lid and there's the "see-through" of the screen while
flip lid is closed. However when I inquired Case Techworks
to see if this would fit my T90, they advised no, and that
I should get the T90 Flip Case (http://www.casetechworks.com/cgi-bin...f01+1030388089) instead.

I really like the "see-through" feature of the convertible case
but it doesn't look like it's available on the T90 Flip Case.

Any thoughts or comments?
