WRC,
Relax, Supersdude is the man. I was just like you, I wanted mine right away and there were a couple delays.....
But,
Supersdude is busy and he sells/jtags/reflows/reballs alot of xbox's. Mine came back a little later then I wanted, but once I went back and thought about the work he did for me (1 JTAG, 1 Reball), I realized this stuff takes time.... Don't forget, he also has a day job.
Be patient, if you show patience and courtesy, he will get back to you. Remember also that this is the week before a holiday, he may be getting ready for or be on vacation.
