If those ASICs were selling as well as they want you to believe they are, they would not be marking the prices down. More and more are slowly realizing ASICs are coming out too late and it's a dead end that you will not make your money back on.
I hear ya, even the USB Block Erupters are going down in price, a few days ago they were selling for 20.50 shipped now a seller has them up for a buy it now of 17.70! (Prices in USD)
