I bought a Modded Xbox from Ozxmods and I am absolutely thrilled with it.
Ozxmods provided a modded unit with an external case mod for switching between 100V and 240V. It looks as if the switch was always meant to be there. Also I have the ability to switch between PAL and NTSC which was important for me as I travel for work, these features make the xbox playable anywhere I go without any external components. I can also watch my DVD's from different regions on different format (system) TV's.
Am I Happy, you Bet.
I cannot recommend ozxbox.com to you highly enough. Their Service was prompt and efficient, they replied to my requests within hours (allowing for time zone differences) and always acknowledged my questions in the same manner. They also sent they unit overseas for me when I ordered it and it arrived well packaged and free from damage.
The Mod chip works flawlessly, games play first time every time and after purchase support has been great, Jason always got back to me with an answer to help me out, so if you want a hassle free, no nonsense modded xbox that will work right out of the box, buy your xbox from Ozxbox.com, you will not be disappointed.
Oh yes, their pricing is very reasonable when you consider that if you bought the modchip yourself, the tools to open up the xbox (assuming you do not already have them) and invested the time to install it, including the case mod for the switch(s)...then you might as well let them do it for you and be sure that it all works when you get it home.
A definitely happy customer,
