Ethernet sheilds are ard version dependent. I can't remember where the 
break was, but after X ard, you had to have the ethernet shield for the 
new ards. Not saying the shield didn't work, but I have the same 
experience as jake, only moreso. I have ordered at least 30 ards in 
various form factors from asian suppliers in the last couple of years. 
One of them might have been bad out of the gate, but I suspect that the 
circuit I was attaching it to was feeding back intermittently since a 
"real" uno blew up attached to the same circuit soon after.
