I also put this post in the reply of an original OP for credit.
Thanks to Saurus and BrownstotheBone, i narrowed my search down to the rubberized hard case from Amazon.Went for the orange case from one dealer who u'll find below.
At first look the orange was not a bright orange but more of a rustic orange which was a plus. The feel of the case was similar to that suede type feel of the OEM DX.
To one responder, no lint from the pocket on the case.
Didn't like the case from BrownstotheBone because of the big cutout for the speaker, but this case actually has separate cuts for the speaker and the mic.
Put on the DX and the first thing that you notice is the negligible size and weight that it adds to the DX. In and out of the pocket and there is no perception of the added case.
Best part was the price. $2.76 + $2.98 S&H = $5.74.
Case comes in black or orange and is much cheaper now. Check the link below. I may order another one or two for safekeeping.
