Have bought from both US and HK.....mainly lenes, software and accessories....paid duty on an couple of ocassions too, still a saving though. Lenses and flash stuff.
Never bought a body though...have been tempted.....I have a good relationship with a London shop and I know if anything goes down on the body, I would have a replacement instantly. Happened once before with camera when travelling it succumb to electronic collapse....was replaced without question...10 month old.
