Febs, this has been my experience, also. At one of our local shops, they have about 8 basses total, none of which have action lower than 1 cm @ the 12th fret.Not surprisingly, those some eight basses have been there for over a year...
Though it is nice to see how a bass is going to hold up. If it can survive the abuse of a GC for over a year, then I'm sure it would hold up for a lifetime of gigging.
