no solder plug and play worth it?

[GmRunner]

well the thing is I do not have a dvd burner so i will probably only be backing up CD-r games. so if i am only going to do CD-r is the plug and play no solder okay? my question tho is how many
(% wise) of PS2 games are dvd? Like what about popular ones liek resident evil code veronica and that samuri game where there r tons of animated movies and whatnot? can i assume all the good games are dvd and thus i will only be able to backup silly ones like bandacoot and whatnot? lol anyway your input is needed as i am about to order soem mod chip off the web and need to know what everyone thinks. o and does plug and play no solder damage or confluct with any aspect of ps2? thanx all
