MiM are very hit or miss, a friend of mine lucked out on a strat that sounds insanely good, I have an american strat and his sounds almost as good as mine, the only difference is mine has a little bit warmer sound because of the rosewood fingerboard.
anyways what do I know I'm a les paul guy, the best advice I can give you on guitars and amps is to try em beforehand. guitars in general are very hit or miss, regardless of how they're set up.
