Okay, I ordered 5 (+3 free) from GameGizmo. I got $10 off coupon code. So, I used that code to pay for the overnight shipping. The chips came in this morning (I placed my order yesterday) without any problems at all. The package didn't has any installation pics, but it came w/ long color wires, solders, and chips. Since GameGizmo has diagram at their site, I have no problem locating them.
I am in the process of chipping my xbox. So far, I am pretty satisfied w/ their product and service.
