It is being distributed by Trek 2000 (makers of Thumbdrive) in Singapore and is retailing for S$100+. Since Trek don’t enforce a Recommended Retail Pricing (RRP) model to the dealers, I can’t give you an official pricing. Right now only 1 capacity is available which is the 8GB.
The Eye-Fi is not officially sold in Singapore so you have to either get it from resellers who bought it overseas or you get it directly from Amazon. The Eye-Fi Pro X2 8 GB cost about S$160 when you get it from resellers in Singapore, it is more expensive, but you do not need to wait 1 to 2 weeks for it as normally they got ready stock. Amazon is cheaper but you have to wait 2 weeks (in my case) for it.
