I just scanned ebay and didn't see an EXACT match, but if you search droid x plaid case, you will find a big variety of similar cases.
Not sure if you are partial to that particular color, but HandheldItems (they are a legit company - purchased many times in the past from them) carries an array of plaid based cases Note: I believe the last one is the one you are looking for.
