I like my Matrix Infinity. I got my v9 as a premod and the company that did which I wont reveal because they sell dms products did a good job. It boots anything I throw at it. I only use the MC Manager with HDLoader. The Crystal Chip needs a hacked firmware but that can be found easily. It would be nice if you reveal what version you have but that does not matter. The Infinity MC Manager is ok but it should improve with the next firwmare revsion. You could chose either one and be happy. Just dont buy that chip by a 3 letter company. I hope this helps.
