[sdiy] Suggestions for stocking parts bins?

[. g . n . w .]

Folks,

Apologies for such a fundamental question.  I'm looking for suggestions 
on a cost-effective method for building up a supply of common components 
to have on hand for projects.  Are there any vendors that can be 
recommended, who sell assortments of resistors, caps etc. that contain a 
decent variety of different values?  Or, am I better off buying large 
quantities of specific values from a place like Mouser?  Any tips would 
be appreciated.
