Hi there, in a previous thread I was asking about reasons for an Xbox owner to get a PS2. Now that I've been utterly convinced (read: GTA:VC,FFX

), I've been reading up about modchips and/or swap methods. I have a couple of questions which I hope you guys might be able to help me out with.
1) I've read that soldered modchips are harmful to the lasers on PS2s. Is this correct? Is it because they change the behaviour of the laser on the PS2? Is it similar to the "pot tweaking" hack on the XS tutorials page?
2) If the issue in question 1) is true, I think I'd rather go for a swapping mod instead -- do these harm the lasers in any way? I'm thinking of getting the Swap Magic 2.0 discs -- which would you recommend to go with it: a flip-lid cover or a no-solder mod? Do they differ in the games supported? Would I still be able to play original PS2 games without hitches?
3) Finally, I read about such 'no-mod swap methods' such as cog/knife/LH -- people seem to refer to a tutorial on ps2ownz.com but I can't find anything there, just a portal site with links to other sites. Is there a good description of these methods? Do any of you use them in conjunction with Swap Magic 2.0?
Thanks in advance for any light you can shed on these issues!
Cheers,
