First of all -- GET JASON TO MOD YOUR XBOX!!!
Here's how it went. I emailed him late afternoon, got an email back at around 7:15 PM. Gave him a call, very friendly, very knowledgeable. He said he had someone else dropping their XBOX off, so he couldn't guarantee it would be done that evening, but I could come by anyway. Dropped the XBOX off at 7:45 PM (he's about 15 min. away). Really nice guy. There was indeed another guy there, who was having his box done. Again, he demonstrated that he's a real pro, made sure that I felt totally comfortable leaving the XBOX with him. Said he'd give me a call when it was ready, either that night or the next evening. Went home. Got a call around 9:15 PM -- XBOX is modded (Xecuter 2.3B lite), tested and ready to go. Jump back in the car, get there around 9:30. Everything is good to go. Chatted for a bit, remembered that I could use a modified .ini file for EvoX -- he emailed it to me as we were talking. I got Home around 10. Everything worked as promised (he even tightened up a few loose cable connections that he noticed inside the box -- I have a refurb from EB).
Cost: $90CAN (included the chip, install & offered extras)
Turnaround : 10/10 (90 minutes from drop off -- with another guy there before me!)
Service : 10/10
Overall : 11/10 -- bonus for the friendly and helpful environment.
I'll be sending more business his way.
