Hi Narayan, have you considered getting the mod done on the canon
I found this link to a Aussie who does the mod at what I think is a good price.

I have had no dealings with this bloke just found his website, but it might be worth dropping him an email.
I was going to send the 350D into Hutech, but have decided to do the mod myself, the replacement glass has been ordered and the daytime filter is on its way, so in a couple of weeks I should have a modded Canon or maybe a useless piece of junk :-))
cheers
David.
