The important thing is to always use the same monitoring gain
and getting used to that. Unless you are moving between different
work locations the absolute calibration is not that critical.

Several people have reported that the reference SPL suggested by
Bob Katz is quite high anyway. This is most certainly the case if
you are in a relatively small listening room with close speakers -
there seems to be a psychological effect that makes it seem unnatural
and unpleasant to have high SPL in small enverinments. 
So unless you go for scientific accuracy the cheaper meters will
probably do.
