I buy multi coated on the UV and Circ-pol but everything else is not multi coated, I ONLY use B+W so the glass is high end, but the other filters I use less and it's not worth the extra money IMHO to bother... (oh except I use the nikon circular polarizer because it's super thin, good quality, and much cheaper than the B+W equivalent, but everything else is B+W I think the quality of the filter glass itself is more important than the coating which is mostly more useful for clumsy photographers who don't keep stuff clean ... haha
