they can ship in 100 units (if you promise them to buy more later) for about usd2.5 / usd3 a unit fob china, add about 50 for the wire transfer, add about 100 for fedex and I don't know how much customs will charge you, but think about 400/500 usdollars grand total delivered to your door.
And if you actually buy more later (about 3000 more) they credit you with the surcharge applied to the first batch.
