As I somehow like to use flash all the time, (with vary manual output) even I set the WB .. will hv different result ..  

Or just set to whatever K value ... then do mild fine tune ..

I agree! It's just a piece of paper/cardboard, depends on how the user uses it and it won't last long anyways, color may vary after long time usage under sunlight or rain etc. I do think post processing for digital photography is essential and can't be avoided.

    very true.  Also remember even if you buy the real Kodak Grey card.  It will age, and give you difference readings over time.

Also, it seems no one agreed on the current Dslr are seeing 18% grey either. (some say 16%, but don't quote me on this one, I am not a scientist.)

Honestly, if a grey card is a matter to you, that means you think the actual reflective index is important and critical. Why risk to buy an informal piece of 18%-like grey card from a non-camera store? Knowing that even you think the color might look the same, they might have a different reflective index though. And if you think that's not too critical, then just save that whatever $5 or $30 and use no grey card la!
