They are approx 0.086 BTC per Avalon chip and 80 to assemble ten to an open source board, and 100 to assemble 20.
Chips are rated at 282 Mh/s each. Not too sure where you've got 2.0-2.5 BTC for 10 from?!
So thats 280 for 5.64 Ghash
About 700,000 chips on order?? 5.64 Ghash x 35,000 in a few months. Is that right?
No, man your addition sucks, that's just the chips as it states clearly above. Then you have 100 Euros if they decide to do the double sided boards or 160 if just the 10 chips per board, plus housing and psu. On top of which you're sending anonymous currency to people you don't know on a bulletin board to buy the chips and then have them send that to another anonymous person in another country to assemble the unit.
But then by August/September who knows what offers will be available.
One things for sure, the BFL crowd won't be making anything like they envisaged.
However, they will be making something ... unlike here as far as they have given details so far.
My BFL Jalapeno is currently mining at 5.368Gh/s on a rpi (faster on my desktop) with cgminer

The one I ordered cost ... $187 ... with shipping.
They are now priced at $274 ...

You make the BFL alternative sound so reasonable. I would venture to say that your experience with BFL and the microsingle is atypical. The experience of a new pre-order buyers at $274 would expect something very different (in terms of shipping time).
I've got no idea when BFL will ship if you order today.
The Jalapeno does, however, already exist and will be shipping in quantity soon.
Here we have a couple of guys who have never made bitcoin hardware before and have 2.25 months left to meet their 'few months' they said in the opening.
That few months isn't going to happen.
Then to top it off they say they are 'going' to sell a device for roughly 10x the price what BFL is shipping soon.
As has been stated before, if they were really trying to make these things and were going to meet a deadline in a little over 2 months from now, they would be providing details about what they are doing.
They don't have any 'great' secrets that will give any competitor an advantage.
Their great secret really simply means turning customers away. Pure and simple.
There's no reason for them to hide, unless they have something to hide ......
