   The amount of frequency drift in the carrier freq of a commercial
FM station is negligible; ditto for a well-designed digital FM tuner.
The main reason for .05 MHz steps in some tuners is that the European
band plan allows for stations at .05 Mhz increments (93.05, for ex.,
is a possible European FM channel).  Some tuners allow you to select
either .2 (US) or .05 (Euro) increments.
   Under some circumstances where the desired station is being
interfered with, some people perceive less distortion when slightly
mis-tuned (96.35 for 96.3, for ex.); this might be a legitimate
(tho not very strong) argument in favor of a non-digital tuner
or a digital tuner with Euro-increment capability.
   Don't believe everything (anything?) the salesperson in the audio
store tells you.  (Ditto Usenet, judging from some recent contributions.)
