Actually, I can't think of any.
Or at least any that matter enough to me to stop me from temporarily losing all logic every time I'm sent pictures of gorgeous Welsh D's for sale. There are a lot of really nice prospects for sale at the moment!
This is Sasha, she's a 4 year old mare, 14.2hh, just started under saddle. And yes, she's for sale if anyone out there (besides me) can't resist a nice pony. She's from the same farm I bought Ginger from and having met her in person, I'd say if anything she seems larger than 14.2hh - she tends towards more of a leggy athletic build. Or maybe it's just that cob personality that's so larger than life making me remember her as taller!
Anyway, here you go, some pretty pony pics for the long weekend:
