See changed secondary Stats before binding an Item

Hi there,

i'm currently looking for an Addon that shows me my secondary Stats (Block, Dodge, Critrating, Attackpower...) before I equip that Item. An example: I see new Boots that I problably could have a use for. My old ones have the following Stats: "+15 agi, +14str, +17sta, 14 Critrating, 220 Armor". The new ones: "31 Critrating, 24 Hitrating, 17 Dodge, 35ap, 234 Armor". Now I want to see my secondary stats with the new Item equiped, perfect would be some sort of color coding for positive or negative changes. I guess the Addon I'm looking for could look like a second Characterscreen including my current equip, the difference would probably be the possibility to virtualy put Items in the Itemslots I have. In case of my example the Boots slot.

Hope I could properly explain what I'm looking for cause english is not my native tongue.

Thanks for your answers. Vampyrate: Thanks for the suggestions, but"Rating's Buster" isn't exactly what I'm looking for and a search via CGs searchmask brought no results for an Addon named "Pawn". The problems I have with the decision between two items are mostly questions like "are 5crit and 6hit worth giving up 7 agi? How about armor? how about dodge rating I loose when changing from agi to secondary stats on items?". Those questions get extremly complicated when considering my 3 forms, cause I play a Feral Druid.

Eldredd: Aye, I guess the Addon I'm looking for has to be writen sometimes in the future. Hope someone with knowledge in LUA gets the same issues I have with Items and decides to write an addon the fits his (and mine ;) ) needs.
