Guys I have been following this thread for a while now. I think it is a great idea that some of you here challenges the elements I have also seen here that it is a little difficult to get your hands on another sensor if you screw the first one up (and it would seem that it is almost certain one would), therefore I decided not to do this on my 450D sensor. But now I have a 450D sensor which is redundant. I don't want to make any sale advertisement here as I am very sure that the moderators would not be pleased with it but if any one interested just send me a private massage. It'd be nice if it does not go to waste.
