i'd get the 02. no reason to buy 03 and start fixing stuff in it. even if the fix costs 3 bucks.
the lo-pro edge has been used by countless guitarists for years and years in the most extreme abuse and kept the guitar in tune
ibanez made this new bridge and messed it up.
if lo-pro can stand vai abuse for so many years, i would't replace it just because its not 2003. guitars are not cell phones:-)
somtimes the older thing is the better.
