theres no room for sentiment when your talking about thousands more to be made by breaking.
the only downside is having to deal with all the timewasters that say "dont break it" and "if i had the cash id buy it" type stuff.
then theres all the clowns that hassle you for a window switch or something equally small and complain when theres a tiny scratch on it and how they could have gotten it 50p cheaper on ebay etc etc .
i had started breaking mine and gave up and changed my mind after being inundated with timewasters
