A few years ago I bought a Iki housing and flash etc from BHphotovideo.com. All the stuff came within a few days. Even counting UPS and VAT it was about 25% cheaper than anything I could find in Europe. That said VAT in Switzerland is only 7.5%.
A few months ago I replaced everything for a new Iki setup 20D housing secound flash, lenses etc. This time I arranged a day stop over in Singapore, prices where slightly higher than BHphotovideo, but no shipping and the VAT is refundable or not charged. Import duty is an optional extra, green or red chanel it is your choice

. Of course you would have to make a dive trip to Asia but if your are looking for an excuse...
