Yeah... it was only a matter of time! I think she's nicknamed me "The Enabler."
So MsBearCtr... are you looking for what's in the picture you posted, or a Pectinia Lactusa? I just happened to get the 3-volume Veron coral book for my birthday the other day (WOW... 17 lbs of books about corals!) and looked up the Pectinia Lactusa. While some of them *kind* of look like a platygyra, the pectinia have much deeper and broader valleys.
I really think the picture you posted is a type of platygyra, and now that you've mentioned the coloration you're looking for, I think I remember seeing that coral on LiveAquaria maybe? At least somewhere I remember seeing a platygyra with pink valleys and purplish/brownish ridges.
If I see one at any of my haunts, should I tell you? I mean... I wouldn't want to be accused of feeding your addiction or anything, but we all have to look out for each other, right?
(Plus I'm done buying for a while, so I have no problem telling you where the good ones are!)
