I don't understand why the crystal is perceived to be so difficult.

The resonator includes two caps. Well Whoopee.
How do they magically pick the right value of caps for your 
circuit?  They don't.
This is one reason, though not the dominant one, that they are not as 
accurate as a properly applied crystal.

A crystal, and any cap within 50% of the right value is more accurate 
than the resonators.
Really, if putting two caps on the board scares someone, then why is 
he doing these sorts of projects?
