Waiting was never an issue for me, I'm prepared to wait a long time.
I've been dealing with grandenigma1 regarding an AD2000 recable, he can confirm the length of time the transaction is taking.
I placed an deposit for a HeadAmp BHSE sometime late 2007 and I'm still waiting. Sure, it is taking longer than I expected, but I know I can get the deposit back anytime if I wanted to. Justin can confirm that I've never complained to him or bugged him about it.
SinglePower told me my amps were ready to ship in Feb. 2008 and took my money. At least one of the amps, the ES-1, should've been shipped long ago.
It does feel like it has been ages and I am not even the one waiting... There was time that we were worried that you would not have the headphones on time. Me personally I am not good with the whole waiting thing....
