Modding my Xbox?

Xbox 360? If so, I'm looking at this. I buy my 360 games but some games aren't worth the price, Soldier of Fortune for example, and therefore I would like to burn it. I think it's a good idea but you should still buy good games and multiplayer games so you can play on Live. I've already bought almost 20 Xbox 360 games and I don't regret it. I like to support the game industry but some games aren't worth the price they retail for.

edit: Ok now I don't think I will be getting one:

Only mod your 360 if you just plan on playing backed up games offline - it sounds too risky.
