Housing Suppliers in Thailand or Asia (Cheaper...)?

Hi, I am in Thailand for a few months and i want to buy a housing for my Nikon D7100. I'm looking for used housings but if i don't found it may be i have to search a new one over here. Do you know if is there an economic option here in Asia?

Thanks!!

Talk to Scubacam in Singapore. They are my go-to source. David and Sanah can work some good deals, and you save the tax on departure (which in this case would cover your flight from BKK). They might even be able to find a second hand housing
