So, I've been thinking about buying an Xbox 360, and then modding in. Should I buy a pre-modded one, buy a new one at a store (probably an elite model), or buy a used console? I'm asking this because I'm not sure which is the easiest to mod, an older system or a newer system. If at all possible, I am going to go with an elite. What Dual Layer dvd's do you recommend that last the longest. I've used a variety of dvd+r's for my original xbox, and some just stop working after a while. Is this a common problem with the dual layer disks?
