Gear -> Stat Spreadsheet?

Hi,

I was wondering if there were any available spreadsheets around where I could plug in gear into a lvl 70 blood elf to see the outcome stats-wise?

I know there are gear rankings around but I'd like to actually see the avoidance/hp differences with respect to the other gear the character is wearing.

I know this exists for hunters but was curious as to whether someone has made one for paladins?

Thanks
