Don't know if this helps...

Here's my identification of the parts. The layout seems to match this identification. I've also included a per-unit price estimation, based on 10,000 unit quantities at digikey.

Top left: NXP Semiconductor 74HC574 (octal D-type flip-flop), about 0.12 USD
Top middle: Atmel ATTiny2313 (8 bit microcontroller), about 0.72 USD
Top right: Silicon Laboratories CP2102 (USB to UART interface), about 2.30 USD
Bottom right: Alpha & Omega Semiconductor AOZ1021 (3A synchronous buck regulator), about 0.50 USD

Stop using branwallets

I bet one of the ICs on the board is the most expensive -- you could look up their prices pretty quickly.

Are ฿itcoins Radioactive?

You must be very near to the truth... and I paid 2.47 BTC for each of mine... Cry

Here's a nice picture of the components on the stick (rev 3):

I've been trying to estimate the margin cost for ASICMINER to produce the USB Block Erupter.

Given that the processing unit that is placed on the stick has similar characteristics to Avalons chips, I'm assuming the cost per chip is also similar. Avalon are selling their chips for BTC0,078 per chip, but I don't know what ~~profit margin~~ markup they are using at that. Let's assume 100%. That means the margin price per chip is BTC0,039, ~4 US$.

The chip is not the only thing on the stick, but the other components are very cheap. Say $1 for the rest of the components, $1 for the PCB and $1 for the manufacturing process. That's a total of $7 per stick.

Thoughts? If you have any other way of estimating the margin cost, please post it in this thread.
