1) Hard to argue that the first USB miners were over-priced when they were selling for $400 on ebay.

2) If you think they are over-priced then don't buy them LDO.

3) Which do you prefer:

   3a) ASICMiner sells USB miner for 0.5 BTC.  Customer sells it on ebay for $400.

   3b) ASICMiner sells USB miner for 1.99 BTC.  Customer sells it on ebay for $400.

[ I bought a USB miner for 1.99 BTC + group buy markup.  I'm happy and unbothered by price changes.  ]
