Noob needz help with Modding

I know this has probably been answered 1000 times but i cant seem to find it. Im looking to mod my xbox 360 to backup my games. Is there any modchips that are available and if so where can i buy it from? I heard of opening it up yourself and flashing the dvd drive by computer but that seems like too much work for my little mind for right now. I also heard of the Xecuter's Blaster360 and was wondering is that the newest mod or are there newer or better ones. Are the modchips all together just fake advertisments? Another question is where could i buy it from if i wanted one? Last but not least is there a tutorial on how to install a modchip. Ive installed a couple before but this will be my first on a xbox 360 and if i do get a modchip will i still need to use my computer or will it work itself out. Sorry to be such a burden on all of you. PLEASEZ HELP
