i just read through the whole thread there, and it is full of bullcrap. someone had his 40d's sensor cleaned and got back his 40d with a new service menu (supposedly). although being told to do so, he never did prove it by at least supplying pictures of this new menu (he said he doesnt have a 2nd camera multiple times... like he is living in a cave...). anyhow, he then reported that he sent it back to service to get a non-service 1.05 firmware on it... even though SEVERAL people told him they would BUY his 40D (with the service menu activated) for money worth at least a NEW 40d.
given these facts i either think the guy was a big idiot or a liar.
