Titus,
Flick a coin... I've not bought a LD but have bought loads of camera equipment from Korea, China, Japan, HK, Sing and the US. I've been charged customs about 20% of the time. It can be a sting - not so much the tax charge (which is fair enough) but the £15-25 charge Parcelforce charge for the pleasure of making that charge!
I wouldn't let that put you off though if you fancy a product - you'd be unlucky and they're very popular and well-rated products.
