If you want a flip case for your HTC EVO but don't like PDair's selection (considering the quality of those cases, who could blame you?), then you might want to check out Noreve's Tradition leather case.
It's more expensive than it would've been if NoreveUSA was still in business because of the exchange rates, but it comes in a wide range of colors and leather types and ships with a removable belt clip.
Prices start at 43€, which is about $60, and shipping time depends on color/type. The black case made of the company's Perpetual Selection leather (shown) will ship immediately, while everything else needs to be handcrafted, which takes up to 15 business days.
I'm a long-time fan of the brand and can attest to the top-notch quality of the cases (I have about a dozen of them for other gadgets), but this one for the EVO looks rather strange because of the way the back is designed.
See what I mean?
In order to keep the flash, camera, and speaker protected, the flap on this case extends very far down the back of the case, which means that when you flip it over to use the phone, there will be quite a lot of leather flapping around over your hand.
The strap, which extends too far up the back of the case in my opinion, seems thick enough to balance the flap's thickness, so I'm guessing that the case shouldn't be too wobbly when placed on a flat surface (unless you attach the belt clip).
Unlike some of the Noreve's other cases, this one doesn't have any slots on the other side of the flap for business/credit cards or extra microSD cards.
