Yeah, I think when you're looking at a £500 item, it would work out at about £650 (for a musical instrument), which is about what they'd be worth in the UK, if not slightly more. So I'm just going to keep my eyes open over here for now.
You do have to pay tax/duty on used or refurbed goods, just the same. Even 'gifts' over £40 incur similar charges, so in this case it's just not worth it.
Damn!
Good job I got out-bid then!
