I've done a bit of research and the Alladin, Chameleon and X-bit look good to me. Just recently I bought the Alladin and it's been gr8!!!
xecuter 2.3 lite , the soderless one is pretty damn good. seriosuly works like a charm and if you want you can take it out and pop it in another xbox.
i got xecuter pro this is the best in my opin and if u look around u well see xecuters name on aloght of stuff
