Flashing with Blaster 360

[netfiend]

I want to order the Blaster 360 to flash my 360 with the Hitachi drive, but I got a few questions:

1) Will flashing the 360 using the Blaster 360 requires power from the 360 or some other external power?
2) If the Blaster 360 uses external power, how do I power it?
3) How do I connect it to my computer? The description said "Imagine using this along with the X360 USB - Firmware modding has never been so simple !
", do I need to x360 usb too?
4) I am in Canada, what's the cheapest or fastest online store to order from?

The Blaster360 is simply an external SATA port , combined with the "Xecuter Connectivity Kit". It extends your SATA port outside of the case, making it easy to access, wihout opening the system. It also includes all the stuff the connectivity kit was. You power the drive with a standard desktop computer power cable. Those are the 4-pin white molex cables that normally connect to hard drives or optical drives.

You will still need SATA ports on your desktop's motherboard, or if you have an older version Hitachi you can use a SATA > USB adapter.
