Hey guys, I'm new on this thread so I wanted to introduce myself.  I first heard of bitcoin back in 2010 and tried some mining but lost interest quickly.  The value of a btc was minuscule and my graphics card was not even good for gaming so I could only make a micro a day or something silly like that.  Anyways, the value popped and I'm still kicking myself for not paying any attention to it last year.  Yesterday I had the opportunity to get in on the terrahash preorder.  I was actually hitting the refresh button on my browser at 11:58 and at exactly midnight the shopping cart opened up.  My order was like #21 but just before forking my hard earned cash over I came to my senses and cancelled it.  I'm mostly interested in the technical aspects of mining and if I can make a profit out of it that's even better.  The way I see it, terrahash isn't much further ahead than any of the other DIYers.  If BKK, the designer of the board isn't even ready to test, I don't see how TH would be.  I've looked at the power, cooling, and control requirements of the Avalon chips and my impression is that the klondike design is going to need a fair amount of work before it's ready for stable hashing.  Instead I've decided to accumulate some BTC and get in on a Avalon chip group buy.  Avalon chips clearly have value, they have already proven themselves capable of driving rigs, while a klondike miner preorder has unknown value.  The feasibility and timeframe are both uncertain.  I would like to buy about 125 avalon asic chips and wait for the board designers to get a working model done.  Then I'll buy the working boards and finish the miners myself or outsource the final production.  Worse comes to worse, I can always sell the ASIC chips at a slight markup to others who don't want to wait for a batch order.
