AH Vendor Buy/Sell Price

[nickyjean]

Hi Guys

With the new AH out there I was wondering if there was a simple addon that when posting/buying in the AH the text of the pricing can be changed or highlighted like this:
Red - if AH Price is lower than Vendor Sell Price (signaling not to post but to sell to a vendor)
Green - if AH price is lower than Vendor Buy Price (Signaling to buy from AH instead of the Vendor)
Yellow - if AH price is higher than Vendor Buy Price (Signaling you may want to sell if it's just loot you wouldn't use)

Any idea if this already exists? I know trade skill master, Auctionator and such exist but I'm hoping for something smaller when I'm on a laptop with less memory.
