1.9 shipped in US
When I purchased the miner, the shipping cost was $300 within the US. So your offer of 1.9 BTC is not higher than the 1.6 BTC offer with local pickup.
$300 shipping San Francisco to US???
The forum seller who sold me the unit charged $300 for shipping, so I assume my shipping cost will be similar. Even if shipping is only $200, I'll choose a local sale and no shipping hassle over an extra $100. :-)
