Dude - I don't recommend anything to you personally, I don't know you, care to know you or care what you do with your money! If this is in reference to some flame you have on this board...I don't care, I didn't read the other statements.
The 360 is a fun machine, there are issues with it, and getting an extended warranty may eliminates one of the biggest issues (crashing). Everything is a cost/benefit analysis, you do what you want with your money. Just providing info to the masses...not to you personally (read above how I much I don't care about you...and my guess, with that attitude, no one really does)
