Greg, actually its the reverse, PEC is more important not autoguideing than with.
If PE is smooth, then a suitably fast guide correction rate can correct the PE drift, PEC is not essential, its a handy bonus. But if guiding is not used, then PEC becomes very important, PE shows up immediately.
Random fast PE variations cause havoc, guiding or not, guiding wont then help a squat and it should be addressed. The only way to fight bad PE is with fast AO, and thats way more expensive than a mechanical fix.
Unless of course the mount is an unfixable nasty cheapy, in which case fast AO turns it into PME, for a lot less money ;-)
