Hello Mr Lindsay,
Here is a complete quote for the purchase of this kit:
* $2220 for the Schneider digitar 35mm lens + Cambo WRS plate
* $203 for the center filter
* $0.00 for shipping (included in selling price: belgian post with insured declared value + tracking number + sign for receipt)
Paypal fee: $73 (3%)
Total amount: $2.496
ps: add $15 if you want an express delivery
Regarding taxes I don't think that there is anything to pay for items coming from the European Community.
To be sure can I suggest you to ask this question to Landscapelover ?
I've sold and send a 75-150mm Mamiya lens the same way to this forum member who is living in Denver, CO
He can surely confirm that no taxes are applied.
