I purchased this one and it is perfect! ebay
Price is great fits ONLY EVO. Now it will be easier to use my Cardiotrainer
If I had to find fault with it is that I can not use a case with it. But I have found Nothing better. Love it. Hope this helps other EVO users. The price is so good I don't think you can make one yourself for the same or less.
It is shipped from Hong Kong and it takes almost 15 days
to get but they do tell you this.
