I've read the FAQ and still need some input as to which chip to get. I have a V7 PS2 and am looking for these things: 1. Price. Hoping to spend less than $40 shipped. 2. Ease of install. 3. Best place to buy. Also, I see that the more expensive chips have the upgradeable Flash memory for future compatibility with new copy protection. Has Sony ever changed copy protection methods on games to render certain modchips unusable? What is the risk of this happening in the future? I see that some chips have a ribbon cable. It seems that the ribbon cable would make for a much easier install than a bunch of jumper wires. Is this true or not? Thanks.
