Hello all, I want to install a mod-chip in my PS2 (v4), and so far I've been eyeing the Matrix Infinity. All I want is to be able to play backed-up games. I've also been looking at the more cheaper Duo Chip, but I don't know if it is any good or not, is it? Which of the two should I buy? Or perhaps there are better chips out there? Money isn't a problem, but I'd rather pay less to fit my needs. Also, which retailer is the most reliable in the US and offers the cheapest prices? Answers to any of my questions is greatly appreciated.
