I'm right there with you Susan! I wanted a R&W male (regular coat), and ended up with a RHT female fluff.

And of all the colors, I really didn't like the RHT too much, but now I love them. Of course, I didn't HATE the RHT, just didn't care for it as compared to the other options. But I have really grown to love Jackie's coloring, and I think she's a beauty. And it's true what they say - the girls are bossy!
If the blue merle is REALLY a turnoff for you, then I would say wait. I guess it comes down to whether you want a puppy now, or are willing to wait for another litter. It does sound like you have other breeders you can work with, so maybe the wait will not be too long. Okay - now that I have basically straddled the fence and argued both sides (not very helpful Jess!) . . . I say go with your gut.
And regarding Pem vs. Cardi . . . sounds like you need one of each!
