Yes, my friend morg and i go to most of them and I agree they are hit and miss when it comes to phibs. Sometimes though, the newts I have seen there have been quite unusual. Over the last few, amongst the standard adult Axolotls and waltls there have been juvenile Taricha torosa, T granulosa, Cynops ensicauda popei (sadly without locality data or I would have snapped them up!) and Triturus pygmaeus so it's always worth a look.
I always think these kinds of expos are driven by a combination of dry goods companies promoting their latest pot skull decorations and coloured sand substrates along with reptile breeders selling their latest colour morphs before they go out of fashion, but it's horses for courses i guess, pardon the pun.
