Ikelite DSLR Canon 450D housing

[Shark 1980]

Hello guys,
I would like to buy "Ikelite DSLR Canon 450D housing".
Do you know where it would be cheap and safe?
(Don´t want to spend 1 300 dollars and then get nothing...)

I am interested especially in shops in GB (now I am in London),
or about this shop: http://www.oceanicfocus.com/catalog/product_info.php?manufacturers_id=18&products_id=3 14&osCsid=3200b2ef4a193e2d666d9d282f7b7518

Have you ever heard about this shop? Is that safe to buy from them?

Thank you

I have used camerasunderwater, here's the linky:
Cameras Underwater: Ikelite housing for Canon 450D camera

i think their service is excellent.
i'm slightly jealous of you getting that housing... what strobe are you going to use?
