Help Flip top or Mod chip

[RonZombie]

Ok I went over both of them for hours now and all I see on here is Swap magic will blow up and destroy a city block but nothing in stone why its so bad. I read that you can play on line with a flip top and swap magic with backups is this true? A friend of mine is a manager at an EB Games and never had a issue with his flip top. Its not a money issue I can't install the mod chip myself and I hate to be without my PS2 while its being installed. So can someone give me a solid reason that the Fliptop is so bad? Thanks, Ron
