Need mod chip for new PS2

[whoeverxxx]

I'm not worried about soldering the chip in.
My biggest worry is wether or not a modchip does what I'm thinking it does in a PS2......Eg.. Does it work with all backuped games and what software is best to use to back up games? I remember there was one that worked far better than the rest with a PS1. Can a computer CD\DVD Rom drive even read the entire PS2
disc? I know they can't with Xbox games. Is there an easy method for the copy protection on the disc or am I worring too much?
Is there a preference of which console to choose from between the standard PS2 and the slim design as far as which one will work the best with backuped games? Is a PS2 harddrive nessasary for some backuped games? I really like the compact design even though it can't use a harddrive, but like I said I'm a newbe to PS2, just heard it was far simpler to backup your games compared to the Xbox by reading forums years ago, almost as simple as the PS1 was but I havent taken an interest in it since then until now becuase of all the good games the PS2 has to offer. I have hardwood floors and alot of company so I don't want to take a chance on ruining a $50 disc, so backup is definitly for me.
