I've bought quite a bit of stuff via Hong Kong and have saved hundreds even with VAT & import duty.

I recently bought 3 of the new pocket wizards and saved around £200 and got charged import & VAT on them. I saved almost £300 on a 50-500 a few years ago. I bought my light meter for £79 when the UK price was £180.

I've probably bought 4 lenses and loads of other stuff and have never saved less than around £50 on UK prices (that's kind of my cut off point for whether it is work the risk of importing over domestic buying)

If you factor in the extra charges and can still save money then the only thing you have to worry about is what kind of warranty you get and whether you will need to return it to Hong Kong or not for the repair, in which case that could swallow up any savings you make.

No idea on how your current choice of lens stacks up for savings.
