I have to disagree. Based on experience, the cost of upgrading an Orville + shipping gives you a brand new H8000Fw for half the price of it. Taxes can and should be avoided as the customer is not buying a new unit, but simply upgrading it. This is the same as shipping for repairs. You should contact an inter national carrier in your country and ask for advice about this. Temporary export for repairs/upgrades is a real possibility.
No other issues to consider, other than *safety* and user presets backup.
