Nobody is replying because there is no answer to that question.
There are 3 companies that make ASIC's for Bitcoin mining
Avalon - SOLD OUT batches 1, 2 & 3 - This means that you can't buy one until they decide to make more
ASIC Miner - Mining with their equipment, not selling it - This also means that you can't buy one
BFL - Taking their sweet ass time - You can buy one, but have to wait in line for it with the 1,000's of other people that have pre-ordered
Those are your current choices.
EDIT - You can't build your own ASIC rig either

So, if I cannot build an ASIC miner on my own, there is anybody who knows if some of those three companies is looking for funding to get a bigger production?
By the time they roll out all of their hashing power, the network will be 100's of TH and if another company comes along, they better have much bigger, faster and better ASIC chips in order for them to be profitable.
