I just got off the phone with the guy. He seems honest enough. Because of bank wires etc its more likely than not my order wouldn't be in the first 20,000 chip batches (but its possible). He felt very confident he could get more Avalon chips quickly though for future units I got a good vibe from the guy overall.

The window for profit is so small here though so if its not in the first batch of 20,000 chips I personally think it wouldn't be worth the risk vs gain. Even if he ordered more chips today which you can assume he will there is no telling if they will beat the other ASICs to market.
